A little boy who was just 10 years old lost his left arm in an accident. Despite that he decided to learn judo. He started his lessons with an old japanese master. The boy was learning well. One thing that bothered him that it's been three month and his master had taught him only one move. "Sensei shouldn't I be learning more moves?" Boy asked "This is the only move you will ever need to know" Sensei repliedboy didn't understand that but believing his teacher he kept training hard. After several months, sensei took boy to his first tournament. To the surprise of the boy he easily won first two matches with his only move. Third match bit difficult than first two still boy was able to win the match. Amazed by his success, boy was now in finals. In final match the opponent seemed to be much bigger and stronger compared to boy. Concerning that this match might hurt the boy referee called a time-out. As referee was about to stop the match boy's sensei intervened. "No," The sensei insisted, "Let him continue." 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. Boy was the champion now. On the way back from tournament boy they reviewed each move in every match. Boy this time summoned his courage and asked "Sensei, how did I win the tournament with only one move?""You won for two reasons," The sensei answered. "First, you've almost mastered one of the most difficult throws in all of judo. and second, the only known defense for that move is for your opponent to grab your left arm."The boy knew that his biggest weakness has now become his biggest strength. 
Sometimes we feel that we have certain weaknesses and we blame god, the circumstances or ourselves for it but we never know that our weaknesses can become our strengths one day.
