Your chances of success are directly proportional to the degree of pleasure you derive from what you do. If you are in a job you hate, face the fact squarely and get out. You may earn a good living, you may have a safe career, but you will never be a success. Find out what you enjoy doing, and your chances of succeeding will be dramatically better. We play the game every day, sometimes without even recognizing that we're doing it. We compete with other people, or other teams, or other companies, not only because it is essential to business survival, but because we frankly enjoy competition. It's fun to be in the game, and it's even more fun to win.
