Ambition means a strong desire to attain success for one's life. All of us have certain ambition. Some have good ambition such as to be a famous singer or an actor etc. Some others have bad ambition. Some want to be rich like Oprah Winfrey.
Some want to be this person and that person, while some others want to be very rich. If one's ambition is noble then he will surely succeed. On the other hand, if one's ambition is selfish and narrow, he will surely fall in the long run. A person with bad ambition may initially be successful. But finally his ambition will be frustrated. Most people have an ambition to get power and influence, wealth, and fame. Sometimes they are successful. Ambition coupled with hard work brings success and benefit. It’s sometimes unsuccessful depending upon the nature of the means. If a person does not go through training, his ambition to be a firefighter cannot be fulfilled. Similarly, a student with an ambition to be a doctor should think carefully. If he does not work hard, he cannot be a doctor. You need to work hard to gain success. Ambition pushes you to reach your goals in life.
In the work field of sports, simple ambition has no meaning. A middle age man in order to be famous like Shane Victorino or Jaromir Jagr must work hard. No matter how old you are in life, strive to be better then you know you can be. To become a professional MLB player like Shane or a professional NHL player like Jaromir your ambition is everything. Ambition should not turn into day-dreams. Nobody can build castles in air. Only an idle man can do it. It is therefore wise to be realistic in our ambition.
