The real competitor is the one who gives all he has all the time. the result is that he works close to his capacity all times, and in so doing, forms an attitude of giving all he has.

This came from the book Tao of Jeet Kune Do which was written by Bruce Lee. He explains that a fighter that gives all even in his limit, it would unleash the reserved power in a human body. He can keep on doing so and is determined to reach the goal or a dream.
