Procrastination and Action Essay Example for Free

Procrastination and Action Essay Procrastination, like all of your behaviors carries consequences. Whether your behavior is conscious or unconscious, you will eventually have to deal with the effects. Its only natural to procrastinate at times but, the way you deal with your procrastination patterns will determine what effects procrastination has on your life. One of the most obvious effects of procrastination is the failure to reap the rewards that would come from taking action. If a student chooses to procrastinate rather than complete school work on time, there can be many terrible effects. Of course, his or her grades could suffer if that particular school or teacher penalizes for late work. Severe procrastination can end in failure if the work is not accepted because of lateness. Even in the best-case scenario, work completed under the stress of procrastination tends to be poorly done. Procrastination can also negatively affect a person’s home life. Imagine you procrastinated and left the dirty dishes in the sink after dinner tonight. That would not be such a big deal, right? Now imagine you did it for a week. Imagine the putrid stench, the mold, and the hours of scrubbing it would take to get rid of the dried food. Procrastination is bad, but procrastination over a long stretch of time is horrific. You might even give yourself food poisoning! Overindulging in procrastination at work will inevitably get you fired. If your boss asks you to do something now and you do not complete it until next week, do you think you will keep your job? Even if you do not lose your job, you will likely receive a bad evaluation and perhaps face a pay cut if you are not completing tasks in a timely manner. If you are fired and you have a history of bad evaluations, you will not likely receive a letter of recommendation from your old job. Without a good work history, it will be difficult or impossible to get another job. When you procrastinate you simple fail to take action on the very things you know will bring you the rewards that you desire. Although you know what you want and even what you need to do to get it, you still have to take action and its usually at this point where procrastination sets in. Because the results that you desire are often something bigger and better than what you currently have, you must step outside your comfort zone to get it. You might have to take actions that you are not comfortable with to which your unconscious mind reacts by protecting you against that which is uncomfortable. Although the short term effects of procrastination might seem as positive the long term effects are almost always negative. Failing to reap the rewards of taking action can have many knock on effects. Taking action on your ideas and desires is one of your most empowering gifts. It is the process by which you can make the intangible tangible. Through your actions and your behavior you create or manage your life. Its not only the direct results of your actions that create the outcomes, but often the very fact that you are actually consciously affecting the conditions of your life. It not just your actions, but rather your failure to take action that will have a greater effect on the rewards you reap from life. From this point of view the effects of procrastination is not just a direct but also an indirect loss of rewards. Every action is a cause set in motion that affects and builds on past and future events to the point, where we can never really determine the actual effect of one specific action. More than anything else, action opens you up to opportunity. Opportunity is rarely the result of you waiting for it. When you put yourself in line with what you want most through your conscious action you expose yourself to opportunity. Its never a case of whether you have opportunities but rather are you noticing the opportunities? But even more importantly, are you using the opportunities or are you procrastinating? One thing is for certain and that is when procrastination becomes a habit you wont even notice all the opportunities on your doorstep. You will live your life in distraction, constantly looking for short term pleasures to avoid the real challenges that will cause you to reap the real results. You will always turn a blind eye to the real opportunities. Those who succeed are rarely the people with the most or the most splendid opportunities. They are the people who saw and realized it. Out of all the negative effects of procrastination and indecision the failure to spot and act on opportunity is probably the saddest. So many people with so much talent fail to live up to their true potential because of procrastination. The rewards you reap from life will be either a direct or an indirect result of your actions or your inactions. Not only will procrastination prevent you from reaping the rewards but your inaction will prevent you from even being exposed to opportunity. Opportunity is knocking but you have to take action and at least open the door. There might be many reasons why a person chooses to procrastinate when he or she knows it is time to complete a task. Whatever the causes, the effects of procrastination can be catastrophic. Procrastination can be harmful at school, home, and work. If a student chooses to procrastinate rather than complete school work on time, there can be many terrible effects. Of course, his or her grades could suffer if the teacher penalizes, work that is sent in late. Even in the best-case scenario, work completed under the stress of procrastination tends to be poorly done. Procrastination can also negatively affect a person’s home life. Imagine you procrastinated and left the dirty dishes in the sink after dinner tonight. That would not be such a big deal, right? Now imagine you did it for a week. Imagine the putrid stench, the mold, and the hours of scrubbing it would take to get rid of the dried food. Procrastination is bad, but procrastination over a long stretch of time is horrific. You might even give yourself food poisoning! Not only will procrastination prevent you from reaping the rewards but your inaction will prevent you from even being exposed to opportunities. Procrastination, like all of your behaviors carries consequences. Whether your behavior is conscious or unconscious, you will eventually have to deal with the effects. The effects of procrastination are something that we all have to confront and deal with from time to time. Procrastination is what derives people from their work, study, and even determination. Focus is what is needed in our every-day lives, and though it is tempting to delay what is needed to be done, no excuse is worth it.

Famous People :: essays papers

Famous People In 1999 Ricky Martin’s debut album hit number one on the Billboard Top 100 charts and also surpassed his other CD sales by selling almost 661,000 copies of his first English language album. That same year two major publishers printed biographies on him. (Griffiths, john 1of 5) Since his Grammy debut in 1999 he seems to have found success in every aspect of his career except in his personal life. Even with all the success he has reaped he unfortunately still suffers from the inability to keep a lasting partner in his life. This problem is seen through interpreting his music, where he expresses his loneliness and feelings about losing love. His loneliness has occurred from putting his career in front of his personal life due to his earliest obsession with having the full attention of his both his separated parents. His need for attention did not start at the beginning of the divorce though, in contrary he received even more attention then normal because both his parents wanted to see him be as happy as possible. With his parents not communicating to each other regularly he was able to get things from one parent that the other previously disapproved of. (Furman 5-7) One of the things he convinced his parents to let him do was acting. While watching other actors on TV he wished that he would one day do the same. He decided at the age of five that he wanted to entertain and his father supported him all the way. For his Father, seeing him perform in school plays and sing in his church choir only proved that letting his son act was the most reasonable thing to do. (Celebrating Hispanic Culture 1 of 4) â€Å"For Ricky being on-stage was synonymous with being loved. It was like having an even bigger family to adore and admire his every move and gesture.†(Furman 7) But soon Ricky’s new and improved â€Å"bigger† family would become a littler bit smaller. A short while after his acting pursuit began both his parents remarried and five new stepbrothers and sisters followed. Since losing most of his parents full attention he dreamt day and night about being a huge star so that, once again, he could just not get the attention of his parents but also of the adoring public all around the world. (Furman 8-9) He didn’t know that the public adoration was just around the corner though.

Lack of Diversity in Management & Coaching in Sports

In recent history it has been evident that some of the most popularize sports in America have been dominated and overran by African American and other minority athletes. In turn when the coaching and management positions in sports are analyzed and broken down, the number of minority coaches and managers in sport are almost non-existent and have been since those sports organization became established. In 2006 Blacks made up about 14% of the population, 12% of all college enrollments, and nearly 24% of all collegiate scholarship athletes.In some major sports, such as basketball and football, blacks make up a great percentage of athletes participating. In 2005 over 55% of all collegiate athletes on football scholarships were Blacks and about 62% of all collegiate athletes on basketball scholarships were Black and this is out of the NCAA’s 328 Division I schools. Despite the large number of Black representing the athletes in collegiate sport, the percentage of African Americans in coaching and administrative position were very small.In 2005 roughly 7% of all head coaches of men’s teams at the nation’s largest universities were black and only 6. 5% in women’s collegiate sports. The numbers are even smaller in the big-time revenue generating sports such as basketball and football. Just to give a breakdown of these percentages, there were only 3 head football coaches at the NCAA’s 119 D I-A schools. What tends to help the racial lines seen been athletes on the field/court of play and the people who are in the position of power.One thing that helps alleviate this barrier is the number of minority assistant coaches in position. The percentage of minority assistant coaches in collegiate sports are far greater that of head coaches in power. It seems that it’s expected to for a white man to be in power and for blacks and other minorities to be in assistant roles that it’s become normal in sports and unquestioned. The authori ty of white head coaches is often legitimized through the eyes of black athletes when its seen that black assistant are taking orders from a white coach.This is an issue that has become to be expected in both collegiate and professional sports (Anonymous, 36-37). It may not be thought about much but there are some racial games that are played. Although the Rooney Rule has at least given minority head coaches a chance to potentially get hired because they actually get a chance to get an interview, many still see it as just a rule put into place to make it seem like everything is equal and to save face from scrutiny about racial issues in sport. In 2003, Mike Millen the president of the Detroit Lions was fined for not interviewing a minority.He was not fined for intentionally not interviewing minority coaches, he actually contacted five different minority coaches and each of them turned the request for an interview down. Each of them felt like the job was already Steve Mariucci and fe lt like they were just being interviewed just so that the Detroit Lions could fill their obligation to interview a minority coach. The problem not only lies with collegiate and professional sports organizations and the issue of not interviewing and hiring more minority coaches and managers but also stems from this minorities feeling that they don’t have a fair shot at the position.Some minorities looking for a head coaching position also have negative feelings towards getting called up for an interview just because of rule that was put into place that forces teams to do this. Some feel like if the Rooney Rule wasn’t in place that general managers wouldn’t go out of there to try and search for minority coaches to interview like that have to do now. A subconscious bias is happening within these organizations because the managers are taking the notion that we’re giving â€Å"them† a â€Å"fair† chance at the position because we are given them a n interview just like everyone else.In reality its being done to help shift focus away from the lack of diversity and make it seem that things are much better in that department and that organizations are treating the issue with an open mind (Nordlinger, J. , 25-26). On the issue of the lack of minority representation in the administration side of sport lacks even more than minority coaches. The hiring of administrators of color has been extremely limited and still continues to be today. In 1999 NCAA reported a combined percentage of minority administrators in position is a mere 10%, which includes all areas of the administrator sector in NCAA D-I sports.This statistic includes both women and men which shows that representation of minorities have been scarce both on and off the field in NCAA D-I sports. The biggest concern with the lack of minorities in top leadership positions in collegiate sports starts with top-level managers themselves such as college presidents, athletic direct ors, and conference commissioners not aggressively pursuing minorities for leadership roles. This not happening will continue to bring up the same issues about underrepresentation in sport period.Putting more minorities in position will lead to more and more minorities potentially getting opportunities for interviews through the passing of knowledge from other minorities alike. The NCAA is taking steps to trying to bridge the gap by planning to open a Minority Institute to develop minorities and give them the necessary skills needed to compete with their white counterparts (Greenlee, 1). I feel that both professional and collegiate sports can do a little more than what is being done to bring more diversity to its organizations and teams within its governing body.The Rooney Rule is a start for sports as a whole period to bring in more minorities, although the rule is only geared toward the NFL it kind of opens the eyes of other leagues to potentially implement a rule or some differen t policies that give minorities an equal shot of obtaining the same position as whites. I believe that clinics or some programs should be set up to help minority coaches and minorities looking to get into the administration side of sport, gain knowledge and skills to help make them more successful as leaders.In turn this could make organization better as a whole because different ideas and not just the same mindset of how things should and could be done within the organization. General Managers and other administrators would get a chance to better interact with a person of minority working within an organization and would be able to gain knowledge from them as well. Depending on how well the minority coach or administrator does and the type of knowledge the person possesses could really open of the eyes of his/her white colleagues and help others get their foot in the door.Ever since minorities have gotten a chance to take on roles such as head coaching positions and in different ma nagement position they have been seen as unsuccessful. I believe that this is because they have had limited opportunities and have not always come into the best of situations with teams that have hired them. Ultimately whites are seen as most successful because they are the majority they have more people in position that are and have succeeded but also more that have ailed. Their successes have been highlighted over their failures and it seems like minority coaches and minorities in top-level management positions failures have been highlighted over their successes. Although the number of minorities hired for coaching and management positions are very limited they will have to be successful in order for them to be legitimatized and given fair shots at getting major positions within sport organizations and leagues.Until minorities represent a percentage that is seen as acceptable in relation the country’s population in America is then where the issue of the lack of diversity in major level positions in sport die out.Works Cited Anonymous, .

Celebrating the Triumph of Charlie Parker Essay - 452 Words

Charles Christopher Parker Jr. was born on August 29, 1920 in Kansas City, Kansas to Charles and Addie Parker. Charlie led a lonely childhood which resulted from his parents separation in 1927 when Charlie was just 7 years old. His father was never around much following the separation. Their house however was just a short walk from Kansas Citys entertainment district which attracted Charlie while growing up. This was to be where Charlie would find his place in the world. While Charlies mother was working, he would walk around Kansas City listening to jazz behind the clubs. Parker would sit around all night listening to his idol Lester Young perform along with the Count Bassie band. It was here that Charlie was developing his†¦show more content†¦To support himself Charlie washed dishes at a local food joint, where he met Buddy Fleet, who was the one who tutored Charlie in playing the saxophone. Charlie would then return to Kansas City due to the death of his father and stayed home for about a half a year while playing in a small band there. Then in late 1939 Charlie joined back up with McShann and moved back to Harlem, where Charlie would meet Dizzie Gillespie. Gillespie would join Charlie and would start to work together and develop a new form of jazz. While Charlie was experimenting with a number of different chords in a jam session he discovered a new approach to improvisation. These new chord progressions and the ever emerging so unds of Harlem, bebop was born. Parker would eventually need a break from New York City and decided to travel to California where he would travel for a couple years. It was during this trip to the west coast that he would get heavier in to drugs and alcohol, specifically heroin which he used as his inspiration. It was while in Los Angeles performing that Charlie would suffer a nervous breakdown, for which he was confined to a hospital bed. He was released in 1947 and returned to New York, where he formed a quintet with Miles Davis and others. Parker would once again tire of New York City and head to Europe for a couple of years, where he would encounter a lot of devoted fans and he also did numerous recordings.
