A young man approached a great swordmaster and said, "How long will it take me to learn the art?". The swordmaster answered, "Ten years". The young man said, "But I am very talented and I will study night and day". The swordmaster answered, "In that case, twenty years". The young man said "Look, you don't get it, I will do anything you say, but I don't have time to waste". The swordmaster answered, "In that case, thirty years".
