Unrealistic Portrayal of Sex in Media - 1364 Words

Television, movies, music, magazines, and the Internet constantly portray sex unrealistically. The media advertises sex, but rarely promotes healthy sexual behavior (sex, sexuality..). Due to the lack of parental guidance, adolescents turn to the media to teach them about sex. Adolescents take their image very seriously and will do anything to be popular and cool- even if it means subjecting themselves to the views and standards that the media has set. On average, adolescents spend twelve hours per week watching television. 70% of teen television shows mention sex and only 10% of those shows talk about the risks and responsibilities that come along with sexual behavior (sex, sexuality). Shows like Jersey Shore, The Secret Life of an American Teenager, The Real World, and 16 and Pregnant target adolescents as viewers. These shows, along with a list of others, glamorize getting drunk and having sex with strangers. Teens that do not have adult guidance may think that this behavior is natural and safe when it is the complete opposite. These shows also promote promiscuous sex, drug and alcohol induced sex, casual sex and friends with benefits. Too much exposure to these kinds of shows can speed up the sexual initiation and early pregnancy (sex and sexuality). â€Å"Friends with benefits† is described as friends engaging in sexual activities without being in a monogamous relationship or without commitment to each other (journal of sex).

Business Biblical Values And Analyze How Productivity,...

I am not terribly involved in stocks, Wall Street, or international trade. The only news I receive about business is when a non-profit is funded or corruption is discovered in a major corporation. Reading Grudem’s book gave me insight into issues businesses face, both internally and externally. His book also claims that every aspect of business is fundamentally good from a Biblical standpoint. The purpose of this paper is to evaluate business under Biblical values and analyze how productivity, profit, and competition can be used and misused in Biblical context. By the definition Merriam-Webster provides, business is defined as, â€Å"the activity of making, buying, or selling goods or providing services in exchange for money.† Business present-day is indeed profitable; albeit riddled with pitfalls. However, from a Biblical stance, an important matter is how that wealth is attained and handled. Luke 16:11 offers a good perspective on this wealth compared to true wealth from God. Luke emphasizes trustworthiness handling worldly wealth in preparation for true riches. (Luke 16:11 NIV) Through reading Business for the Glory of God, Grudem is focused much more on the making, buying, and selling aspects of business more than the profit it generates. Creating, buying, and selling are all topics spoken about in the Bible. Each of these began as a gift from God and have become sullied by sin.

Community is where one finds a place to belong and a purpose to pursue. It can mean the difference between soaring with greatness or simply floating along. It is where leaders find their passion to shine and their reasons to thrive. We will write a custom essay sample on Bba Application Essay or any similar topic only for you Order Now The Emory Concert Choir community is no different, and it is where I have found my own passion and purpose to grow and thrive. The Emory Concert Choir is a family of diverse individuals who join together to fill each other’s lives up with song and laughter. It is where each of us has found our identity and expresses our passion for music. Each precious breath that escapes between our lips echoes through the concert hall and is filled with our pride and joy. However, music is not a treasure to be guarded from others, but is instead a food for the soul that should overflow. Therefore, I have thusly devoted myself to let our music be known to the Emory community as our Publicity Chair. In order to increase our campus awareness and allow a larger number of students to enjoy our concerts, I have started a number of initiatives since being appointed. During my freshman year, I noticed a lot of listeners came up after our concerts to express their gratitude. Many claimed to have been overwhelmed with joy and loved the beautiful sounds. Yet, many of these faces were not seen during the following concert. I realized that the problem lies within the lack communication of information; many simply did not know the date of our next concert. In order to increase communication, I began collecting email lists after each concert for those who wished to be informed of our future concerts. Furthermore, our new YouTube pages and Facebook pages will now allow us to utilize social media to engage with the Emory community. These new tools will help us keep the Emory community informed of all our future ventures. However, awareness does not end with simply communicating information. It is equally important to develop and maintain an image and identity of our Choir as a whole. Just as a company advertises its brand image, we too plan on promoting our choir’s image. During the academic year of 2012-2013, one of my largest initiatives is to identify the key characteristics of our choir, and create a campaign to promote that image. We have already begun designing apparel for the choir and revamping our website. The efforts made here will help shape Concert Choir’s place in the Emory community for the years to come. Over the past year, Emory Concert Choir has transformed from a group of singing strangers, to a family of friends supporting a common goal. I now know my role in improving our Concert Choir family and I know I have the capacity to achieve such greatness. How to cite Bba Application Essay, Essay examples

Ethical and Legal Obligation System †Free Samples to Students

Question: Discuss about the Ethical and Legal Obligation System. Answer: Introduction: Legal obligations are enforced by law while ethical obligation is done because it is the moral thing to do. In the SOCOG case, the management had a legal obligation to make its website accessible to all users. Given that accessibility is a public requirement, the management was legally required to consider accessibility standards when developing the website to ensure all people including the visually impaired could access it. With respect to ethical obligations, enhancement of quality of life is the main element of ACS Code of Professional Conduct that is relevant to SOCOG case. Under this value, professionals are required to ensure equal access to benefits gained from ICT by all stakeholders. In accordance to this value, SOCOG management has to recognize that ICT plays an instrumental role in enhancing quality of life of people especially those with disabilities (ACS, 2017). As such, the management has an ethical obligation to develop a website that accessible to all users. ACS Code Relevance The Primary of public interest Relevant. The interests of the stakeholders impacted by the website have to be considered. Enhancement of quality of life Relevant. Management has to recognize the role the website plays in enhancing the quality of life of people. Honesty Not relevant. Public trust is not an element of the SOCOG case. Competence Relevant. The management should provide a website the meets the needs of users. Professional Development Not relevant. The management doesnt have to stay informed on emerging technologies. Professionalism Relevant. The management has to a role to improve public confidence in the website. If the ACS Code of Professional Conduct was observed, the management would have recognized the right of all people to have access to the website, encourage the members to be professional and considerate of others hence create an accessible website that could be accessed by all people. It is important for IT professionals to join a professional society as they provide continuing education opportunities and information that keeps them updated on industry standards and best practices (Wenger, 2011).

The Four Core Journalism Courses

The Four Core Journalism Courses Photo by Ana Luisa Pinto It doesnt particularly matter which university you attend. For the overwhelming majority of schools, a major in journalism will either require or strongly recommend the following four courses in order to graduate. These courses will cover basic media and news information, the first amendment rights and ethical issues that journalists face in the field, alternative story formats such as photography, and actual reporting on the school newspaper. When put together, these classes provide the basis for the future of your career. They provide the meat and potatoes to your education and your writing. If you find that the school you attend doesnt include these generic courses (or a form of them) you should probably consider reading up on the subjects yourself. Your reporting and writing skills depend on it. 1. An Introduction to Journalism In this course, youll read the famous books. You know, Seabiscuit and All the Presidents Men. Youll talk about the future of journalism and the possibility that print media may not exist by the time you graduate. Youll talk about well-known ethical issues and the people who went against the rules of journalism, including Stephen Glass. Youll probably watch several groundbreaking movies. Youll also be expected to write, even if it isnt very much. Here, youll learn your basic reporting skills and youll get an overview of what the industry wants and needs from you. Youll practice with media, and talk about groundbreaking stories like those involving Richard Nixon. Basically, this class exists to help you familiarize yourself with the major. If, after taking it, you want to move forward, youll begin learning about the footwork of reporting itself. This is where the academic writing starts to come into play. 2. Journalism Ethics This course is all about the court cases and legal issues that surround the journalism career path. Youll get the answers to important questions, such as when to go undercover, when to use anonymous sources, and how to avoid slander or libel. This will feel very much like a legal class, but youll get into interesting discussions that help enhance your understanding of the field. Journalism is complicated, and sometimes messy. This class helps make it a bit clearer. When it comes to writing, youll probably need to develop a few reports. Youll also need to be able to identify mistakes in someone elses writing process, by reading their story and pointing out the ethical flaws. After passing this class, youll be ready to start doing some writing yourself. 3. Visualization in Journalism This class is about writing, of course. But its also about media. Here, youll learn photography and videography skills. Youll also learn how to utilize social media and blog posts. Basically, youre going to learn how to tell a story without having to write an actual story. Writing as a journalist is, essentially, one of the most difficult forms of writing that you can attempt to tackle. You need to be succinct, specific, prepared. This class allows you to take a break and explore your other options. Multi-media journalism needs to be every bit as succinct and specific, but it can also be pleasing to the eye. It gives readers the opportunity to take a break from the long blocks of text, and instead learn from charts and tables. 4. The News Room Now, it all comes to life. Youve been introduced to the subject, youve been given the information you need to move forward, and now youre actually in the room and ready to write. Here, youll gain essential knowledge about the field in which you want to work. Youll be able to use a hands-on approach to interview subjects and share your pieces. Youll also be able to take advantage of your visualization knowledge to create charts and graphs. In addition to experience in the field, working in a news room will give you the opportunity to work with a full staff. Most of your coworkers will be students, life yourself, trying to fulfill their requirements. But others will be paid interns, who have been on the paper for more than one year and are working to improve it before they graduate. You can choose to get more involved in the news room than your degree requires, or you can decide to get an internship that allows you to get your foot in the door at another publication. Either way, now is the time to get real, in-depth experience in order to improve your writing before receiving your degree. These courses take you on a journey, and they take your writing on a journey, as well.

Converting Cubic Inches to Cubic Centimeters

Converting Cubic Inches to Cubic Centimeters Cubic inches (in3) and cubic centimeters (cc or cm3) are common units of volume. Cubic inches is a unit used primarily in the United States, while cubic centimeters is a metric unit. This example problem demonstrates how to convert cubic inches to cubic centimeters. Cubic Inches to Cubic Centimeters Problem Many small car engines have an engine displacement of 151 cubic inches. What is this volume in cubic centimeters? Solution: Start with the conversion unit between inches and centimeters. 1 inch 2.54 centimetersThat is a linear measurement, but you need a cubic measurement for volume. You cannot simply multiply this number times 3! Instead, you form a cube in three dimensions. You may remember the formula for volume is length x width x height. In this case, length, width, and height are all the same. First, convert to cubic measurements:(1 inch)3 (2.54 cm)31 in3 16.387 cm3Now you have the conversion factor between cubic inches and cubic centimeters, so youre ready to complete the problem.Set up the conversion so the desired unit will be canceled out. In this case, we want cubic centimeters to be the remaining unit.volume in cm3 (volume in in3) x (16.387 cm3/1 in3)volume in cm3 (151 x 16.387) cm​3volume in cm3 2474.44 cm3Answer:A 151 cubic inch engine dispaces 2474.44 cubic centimeters of space. Cubic Centimeters To Cubic Inches You can reverse the direction of the volume conversion easily enough. The only trick is to make sure the correct units cancel out. Lets say you want to convert a 10 cm3 cube into cubic inches. You can use the volume conversion from earlier, where 1 cubic inch 16.387 cubic centimeters volume in cubic inches 10 cubic centimeters x (1 cubic inch / 16.387 cubic centimeters)volume in cubic inches 10 / 16.387 cubic inchesvolume 0.610 cubic inches The other conversion factor you could have used is: 1 cubic centimeter 0.061 cubic inches It does not matter which conversion factor you choose. The answer will come out the same. If youre not sure youre doing the problem correctly, you could work it both ways to check yourself. Check Your Work You should always check your work to make sure the resulting answer makes sense. A centimeter is a smaller length than an inch, so there are many cubic centimeters in a cubic inch. A rough approximation would be to say there are about 15 times more cubic centimeters than cubic inches. A value in cubic inches should be much smaller than its equivalent value in cubic centimeters (or, a number in cc should be over 15 times bigger than the number given in cubic inches). The most common mistake people make doing this conversion is not cubing the value being converted. Dont multiply it by three or add three zeros to it (three factors of ten). Cubing a number is multiplying it by itself three times. The other potential error is in reporting the value. In scientific calculations, its important to watch the number of significant digits in an answer.

Fresh mothers will not be required to take part in this study but only mothers who have at least one other child. A sample of about 200 mothers will be selected for this study. The sample will be representative of all the population. Mothers will have their blood pressure measured to ascertain that they are healthy to take place in this study. The child’s brain development will be measured using the Magnetic Resonance Imaging (MRI) which measures the brain and behaviour development. This will be done as the child grows, probably up to 12 years. Further, the kids will have their IQ tested through simple tasks, their social behaviors and their computation skills. All this measurements will be recorded and put into a computer package for analysis. Based on the kind of fish his/her mother was consuming, the level of the IQ, their social behaviours and computing skills will be compared. The level of the MRI will say whether that certain kind of fish will have detrimental effects. Pregnant mothers are classified as vulnerable people thus; their protection from harm will be a priority. Further, their privacy will be protected to the highest level. Also, they will be taken through all the information concerning this study so as to make an informed decision about taking place in the study. No coercion will be used at

Misuse of juveniles in detention centers Research Paper

Misuse of juveniles in detention centers - Research Paper Example These problems cause degradation of the child’s mental and physical health which is explained along each of the issue. At the end, some suggestions are given along with useful tips on how to bring reform and betterment to the system. The conclusion stresses the need to realize the plight of such children and do something about their situation. Keywords: juvenile, detention, sexual abuse INTRODUCTION Juvenile refers to a person who is not yet an adult. The law defines a juvenile to be a person who cannot be held responsible for a crime and cannot be subjected to the sentences reserved for adults. They have separate courts for trials called the Juvenile courts. All the countries have different age definitions for adulthood, but on average we can set the general threshold at 18 years of age. Detentions can be handed to juveniles in juvenile courts over a variety of offenses but these detention terms are different and more lenient as compared to the normal detentions handed out to adults for the same offenses (Krisberg, 2004). There are some laws that are exclusively for juveniles, for instance laws that relate to purchase of alcohol or pornography. The sentences vary in nature from community work to therapy and group discussion behaviors. Tough sentences are only carried out in cases where the crimes are of a significant nature. Though in some developing countries juveniles are send to same prisons as adults. Even in the developed countries, some people are of the view that teenagers should be send to same prisons as normal adults as their crimes have the same repercussions in society. HISTORY The world’s first Juvenile court opened in 1899 in Chicago (Glenn, 2010). Before the nineteenth century juvenile criminals were convicted under the same laws and were termed as young adults. After the advent of the first Juvenile court, the international community eventually realized the need for such courts and separate detention centers. The need arose becaus e when these gullible children were put into prisons where their inmates were mostly seasoned criminals, they came out of the prisons as ones themselves because of the negative influence of those criminals. Some developing nations still don’t possess such separate facilities though. Juvenile courts also take care of the welfare of the children who are abandoned, poor or neglected. Sometimes, crimes such as murders and shootings linked to juveniles are tried in adult criminal courts partly because of the nature and frequency of such crimes and partly because of the public outrage over such crimes (Anderson, 1998 May-June). MSTREATMENT OF JUVENILES Children are an extremely vulnerable class both mentally and physically and therefore, are at the risk of being exploited both outside and inside of detention centers. The main purpose of juvenile detention centers is the rehabilitation of the children. It means that they should be provided with an environment where there problems ca n be handled in a way that makes them give up the habit or act that forced them to end up in the detention center. For example, if the child was convicted for drug abuse, health care should be given to him along with therapy sessions group discussion sessions. But there have been increasing instances where the children have been handled in ways that comes under the

An audit on the appropriate completion of the venous thromboembolism Dissertation

An audit on the appropriate completion of the venous thromboembolism (VTE) risk assessment and adequate thromboprophylaxis durin - Dissertation Example Certain patient subsets display VTE pathologies of idiopathic causes, with no apparent identifiable risk factors. Therapeutic anticoagulation is the cornerstone of management in all patients with VTE, in many cases, standard anticoagulants such as heparin are included as therapeutic options in normal practice. (Schulman et al 2009) Adjunctive treatments, such as thrombolysis and the use of vena cava filters, are prescribed in certain cases. Pregnancy is among several risk factors for deep venous thrombosis, in addition to minor injuries and surgery. (Van Stralen et al. 2008) But those with a familial history of thrombophilia-related blood conditions are at an increased risk. (American College of Obstetricians 2000) Most physicians do not recommend general screening for the patient population at large, and several studies attest to the need for a regimen of targeted testing for VTE conditions only when a battery of predisposing factors is extant. ( Robertson et al. 2006) (Osinbowale e t al. 2010) Of particular instance in this case is the degree to which proper screening is conducted for pregnant women, both upon admittance to Maternity, and postpartum. SCREENING Diagnostic testing for inherited or acquired thrombophilic conditions is advisable in the presence of personal or family history indicating heightened risk factors. The Factor V Leiden and prothrombin G20210A mutations are the most common genetic thrombophilic disorders, and antiphospholipid antibody syndrome is the most clinically significant acquired defect. Venous thromboembolism often results from the interplay between a series of risk factors. 50% of pregnant women with also exhibit thrombophilia. (Nelson-Piercey 2004) (Zotz et al. 2003) Understanding these VTE risks increases the probability of timely prevention and diagnosis. Virchow’s triad refers to 3 abnormalities that promote thrombogenesis: hypercoagulability, stasis, and endothelial dysfunction or injury. (Van Stralen et al. 2008) (Os inbowale et al. 2010) Several predisposing factors alter ? 1 components of Virchow’s triad. In a systematic analysis of 1231 consecutive patients treated for VTE, 96% exhibited > 1 recognized risk factor. Venous thromboembolism risk factors as may be hereditary or acquired. (Osinbowale et al. 2010) (Dresang et al. 2008) Osinbowale et al. 2010 Provides a ranking of predisposing risks from to lowest to highest in terms of probability: 1.) Obesity LOW 2.) Elderly 3.) Varicose veins (Varicosity) 4.) Laparoscopy 5.) Stasis (Immobility, due to long-term bed rest) 6.) CV catheterization 7.) Any other medical condition requiring hospitalization 8.) Previous VTE states 9.) Paralytic stroke 10.) Hormone Replacement Therapy 11.) Oral contraceptives, and pregnancy itself 12.) Arthroscopic knee surgery 13.) Malignancy and chemotherapy 14.) Spinal Cord injury 15.) Multiple traumas 16.) Major general surgery 17.) Major orthopedic surgery 18.) Long bone fractures, or fractures of hips and pe lvis. HIGH Clinical examinations may prove unreliable, therefore decisions in terms of treatment and/or screening tests must be based upon signs, symptoms, and preexisting risk factors. In this manner, patients are grouped into low, moderate, or high clinical probability of risk. (Sandler et al. 1984) Clinical symptoms of VTE disorders may be subtle and difficult to distinguish from gestational edema, though pain, warmth,

What is scalability ?

What is scalability ? ABSTRACT: The rapid development of large clusters built with commodity hardware has highlighted scalability issues with deploying and effectively running system software in large clusters. The concept of scalability applies to business and technology. In this the base concept is consistent i.e., the ability for a business or a technology to accept increased volume without impacting the revenue variable costs. For example in some cases the variable cost will increase and reduce the revenue variable costs. INTRODUCTION TO SCALABILTY: It is a performance measure for the execution of the software that refers to its ability to accommodate expanding traffic measures like number of users, activity of each user and so on. In telecommunications and software engineering, scalability is a desirable property of system, network, process which indicates its ability to either handle growing amounts of work in a graceful manner or to be readily enlarged. For example, it can refer to the capacity of the system to increase total throughput under an increased load when resources are added. Scalability is generally difficult to define and in some case we define the specific requirements for scalability on some important dimensions. It is a highly significant issue in database, routers and networking. Scalable system is the system whose performance improves after adding hardware proportional to the capacity added is called scalable system. An algorithm, design, networking protocol, program or other system is sad to scale if it is suitably efficient and practical when applied to large situations. If the design fails when the quantity increases then it does not scale. IMPORTANCE OF SOFTWARE SCALABILITY: Software scalability analysis is an important issue for most businesses. It is essential that as the customer base increases, the system has to deal with significantly increased loads, the system is designed to handle the increased traffic so that the users do not encounter unacceptable system performance. Scalability is an important goal for many software development projects and software installations because without scalability success might be hampered by poor performance as observed by end users. MEASUREMENT FO SOFTWARE SCALABILITY: The various dimensions by which the scalability can be measured are: Load scalability: it is the ability of a distributed system to easily expand and contract its resource pool to accommodate heavier or lighter loads. Geographic scalability: It is the ability to maintain performance, usefulness, or usability regardless of the expansion from concentration in the local area to a more geographic pattern. Administrative scalability: The ability for an increasing number of organizations to easily share a single distributed system. Functional scalability: The ability to enhance the system by adding new functionality at minimal effort. DESIGN FOR SCALABILITY: It is often advised to focus system design on hardware scalability rather than on capacity. It is typically cheaper to add a new node to a system in order to achieve improved performance than to partake in performance tuning to improve the capacity that each node can handle. But this approach can have diminishing returns (as discussed in performance engineering). For example: suppose a portion of a program can be sped up by 70% if parallelized and run on four CPUs instead of one. If ÃŽ ± is the fraction of a calculation that is sequential, and 1 − ÃŽ ± is the fraction that can be parallelized, then the maximum speed up that can be achieved by using P processors is given according to Amdahls Law:. Substituting the values for this example, we get If we double the compute power to 8 processors we get Doubling the processing power has only improved the speedup by roughly one-fifth. If the whole problem was parallelizable, we would, of course, expect the speed up to double also. Therefore, throwing in more hardware is not necessarily the optimal approach. WEAK v/s STRONG SCALING: In the context of high performance computing there are two common notions of scalability. The first is strong scaling, which is defined as how the solution time varies with the number of processors for a fixed total problem size. The second is weak scaling, which is defined as how the solution time varies with the number of processors for a fixed problem size per processor. EXAMPLES: A scalable online transaction processing system can be upgraded and can be used to produce more transactions by means of adding new processors, devices and storage that can be upgraded easily. It is also called as database management system. If the size of the necessary routing table on each node grows as O (log N) then the routing protocol is considered as scalable with respect to the network size where N is the number of nodes in the network. The distributed nature of the Domain Name System allows it to work efficiently even when all hosts on the worldwide Internet are served, so it is said to scale well. Some early peer-to-peer implementations of Gnutella had scaling issues. Each node query flooded its requests to all peers. The demand on each peer would increase in proportion to the total number of peers, quickly overrunning the peers limited capacity. Other P2P systems like Bit Torrent scale well because demand on each peer is independent of the total number of peers. There is no centralized bottleneck, so the system may expand indefinitely without the addition of supporting resources. SCALE VERTICALLY v/s HORIZONTALLY: Methods of adding more resources for a particular application fall into two broad categories: 1) SCALE VERTICALLY( SCALE IN): To scale vertically (or scale up) means to add resources to a single node in a system, typically involving the addition of CPUs or memory to a single computer. Such vertical scaling of existing systems also enables them to leverage Virtualization technology more effectively, as it provides more resources for the hosted set of Operating system and Application modules to share. Taking advantage of such resources can also be called scaling up, such as expanding the number of Apache daemon processes currently running 1) SCALE HORIZONTALLY (SCALE OUT) To scale horizontally (or scale out) means to add more nodes to a system, such as adding a new computer to a distributed software application. An example might be scaling out from one web server system to three. As computer prices drop and performance continues to increase, low cost commodity systems can be used for high performance computing applications such as seismic analysis and biotechnology workloads that could in the past only be handled by supercomputers. Hundreds of small computers may be configured in a cluster to obtain aggregate computing power which often exceeds that of single traditional RISC processor based scientific computers. This model has further been fuelled by the availability of high performance interconnects such as Myrinet and InfiniBand technologies. It has also led to demand for features such as remote maintenance and batch processing management previously not available for commodity systems. The scale-out model has created an increased demand for shared data storage with very high I/O performance, especially where processing of large amounts of data is required, such as in seismic analysis. This has fuelled the development of new storage technologies such as object storage devices. TRADEOFFS: There are tradeoffs between the two models. Larger numbers of computers means increased management complexity, as well as a more complex programming model and issues such as throughput and latency between nodes; also, some applications do not lend themselves to a distributed computing model. In the past, the price differential between the two models has favoured scale out computing for those applications that fit its paradigm, but recent advances in virtualization technology have blurred that advantage, since deploying a new virtual system over a hypervisor (where possible) is almost always less expensive than actually buying and installing a real one. CONCLUSION: Scalable system software has become an important factor to the RCF for efficiently deploying and managing our rapidly growing Linux cluster. It allows us to monitor the status of individual cluster servers in near-real time, to deploy our Linux image in a fast and reliable fashion across the cluster and to access the cluster in a fast, parallel manner. Because not all of our system software needs can be addressed from a single source, it has become necessary for us to use a mix of RCF-designed, open-source and vendor-provided software to achieve our goal of scalable system software architecture.

Learning to Control My Obsessive Behavior Essay -- Personal Narrative

Learning to Control My Obsessive Behavior Reflecting on my childhood, I realize that I must have been the only eleven-year old to receive ulcers and migraines on a regular basis. From what the doctors informed me, these medical problems were not from lack of sleep or nutrition but from excessive stress, the kind of stress that middle aged people endure due to their job, kids, or even taxes. The interesting thing is that my home life was perfectly secure. I couldn't have asked for a better family. My mom raised me as a well-rounded individual as she had me constantly involved in clubs, sports, and music. I had many good friends, and even attended a safe school. Despite all of these factors, I insisted on worrying myself sick daily. I would be compulsive and obsessive about every little detail in life such as, my dog needing a flea bath, my neighbors getting along, or losing material possessions. I would be compulsive and obsessive about every detail in life. I demanded cleanliness and organization at all times. This meant tha t if things were not done clean around the house, than without question, I would clean it myself. I would work on my homework until it was totally finished, even if it meant staying up all night. Though my sports and friends were a form of release and relaxation, I was never able to reach this point without being subconsciously concerned with other things. My primary concerns in life were beyond petty. I distinctly remember a day when I was at the elementary level. I was going to have a friend over after school for the first time. From the moment I woke up until she left my house, I was constantly fretting on my house being clean enough, and if she was having fun. I tried so hard to make a good impression ... ...while still having a wonderful day. Two years ago I would have never considered being spontaneous before finals week and now I am having the time of my life while successfully squeezing in the boring stuff. We may think a change such as this may disrupt that perfect GPA or cause one to get into trouble. Though for me, these changes are for the better. I have reorganized my priorities, and I can make more carefree decisions about how I spend my time. I know now that life is so abundant with random opportunities and beautiful people. We must soak up every experience that comes our way. Education isn't always about studying for a letter grade to impress the parents. I intend to study abroad next year and while putting my educational skills to use, I plan on adding to my lifelong memory book and practicing that "we'll cross that bridge when we come to it" attitude.
