A 10-year-old boy lost his left arm in an accident. He decided to learn judo.
The master taught him only one move in three months.
He always said, ”This move is all you need to learn.”

One day, the boy took part in a tournament. He won the first three matches easily.
The boy felt surprised. And he was now in the final. His rival was much stronger.
Nobody but the master thought the boy could win.
The boy actually won the tournament.

The boy asked,”How did I win with that one move?”
The master answered,”That move is the hardest throw in judo.
The only defense for it is to catch your left arm.”

You see, the boy’s weakness was also his strength.
