A young Boy (Differently abled)

A young boy who tragically lost his arm in a devastating car accident. Years went by but his self-confidence was left behind. One day his parents decided to move somewhere new to foget his sorrow. So he started packing his clothes from old boxes and he came accross an old martial art book and some magazines and from there he quickly signed up to study JUDO. He began his lesson with an old Japanese judo master. He was doing well but, he couldn't understand. After three months of training the master had taught him only one move. Finally the boy asked his master shouldn't I be learning more moves? Then the master replied that this is the only move you know but, this is the only move you'll ever need to know. He couldn't understand but believing in his teacher he kept training. Few months later master took his boy to his first tournament with everyone seated and his parents were also present there he surprised himself by winning his first two matches but, next proved to be a greater challenge when he faced a stronger opponent. Concerned for the boys safety the referee called a time out. He was about to stop the match but Japanese master interviened and said him ( referee)let them continue. Soon after the match resumed and 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. One the way home boy asked his master what was really on his mind how did i win the tournament with only one move? You won for two reasons first you've almost mastered one of the most difficult throws in all of judo. Second the only known defence for that move is for your opponent to grab your left arm. The boy's biggest weakness had become his biggest strength.
