Sometimes our biggest weakness can become your biggest strength. Take, for example, the story of one 10-year-old boy who decided to study judo despite the fact that he had lost his left arm in a devastating car accident.
The boy began lesson with an old Japanese judo master. The boy was done well, so he couldn't understand why, after three months of training, the master had taught him only one move.
"Master," 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. 师傅回答说：“这是你惟一知道的动作，但也是你惟一需要知道的动作。”
Not quite understanding, but believing in his teacher, the boy kept training.
Several months later, the master took the boy to his first tournament.
To his surprise, 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.This time, his opponent was bigger, stronger, and more experienced. For a while, the boy appeared to be overmatched. Concerned that the boy might get hurt, the referee called a time-out. He was about to stop the match when the master intervened.
令这个男孩不可思议的是，他轻易赢了头两场比赛。第三场比赛似乎更难，但他的对手在 比赛中开始失去耐心，向他冲过来，而这个孩子立即用他学过的惟一一招击败了对手。就 这样稀里糊涂地，他进入了决赛。 这一次，他的对手更壮、更强，也更有经验。有那么一阵，男孩似乎低档不住了。考虑到 男孩可能会受伤，裁判叫了暂停。他正准备停止比赛的时候，男孩的师傅阻止了他
"No," his master insisted, "let him continue." “不能停，”他说，“让他继续比。”
Soon after the match resumed, his opponent made a critical mistake: he dropped his guard. Instantly, the boy used his move to pin him. The boy had won the match and the tournament. He was the champion.
On the way home, the boy and his master reviewed every move in each and every match. Then the boy summoned the courage to ask what was really in his min.
"Master, how did I win the tournament with only one move?"
"You won for two reasons," the master answered. "First, you've almost mastered one of the most difficult throws in all of judo. Second, the only known defense for that move is for your opponent to grab your left arm." “你获胜有两个原因，”师傅回答道：“第一，你已经基本掌握了柔道当中最难学的一个 动作。第二，要对付这个动作，你的对手惟一可以做的就是去抓你的左臂。”
The boy's biggest weakness had become his biggest strength.
