Sometimes your biggest weakness can become your biggest strength. Take, for example, the story of one 10-year-old boy who decided to study judo（柔道）though he had lost his left arm in a serious car accident.

The boy began lessons with an old Japanese judo master. The boy was doing well, but he couldn't understand why, after three months of training, the master had taught him only one move.

“Teacher, "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 teacher replied.

Not quite understanding, but believing in his teacher, the boy kept training.

Several months later, the teacher took the boy to his first competition.

Surprising himself, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent（对手）became impatient；the boy skillfully used his one move to win the match. '

Still amazed by his success, the boy was now in the finals.

This time, his opponent was bigger, stronger, and more experienced. For a while, the boy appeared to be overmatched. Thinking that the boy might get hurt, the referee（裁判）called a time out. He was about to stop the match when the teacher said to him, “No, let him continue.”

Soon after the match restarted, his opponent made a big mistake. At once, the boy had won the match and the competition. He was the champion.

On the way home, the boy and teacher talked about every move in each and every match. Then the boy gathered the courage to ask what was really on his mind.

“Teacher, how did I win the competition with only one move？”

“You won for two reasons,” the teacher answered.

“First, you've almost mastered one of the most difficult throws in all of judo. Second, the only known defense（防御）for that move is for your opponent to catch your left arm. ”

The boy's biggest weakness had become his biggest strength.
