"Sir," the boy finally said, "shouldn't I be learning more moves?"
"This is the only move you know, but this is the only move you'll ever need to know," the master replied.
Not quite understanding, but believing in his teacher, the boy kept training.
Several months later, the master took the boy to his first tournament. Surprising himself, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent became impatient and charged; the boy deftly used his one move to win the match. Still amazed by his success, the boy was now in the finals.
