Don't Quit Skating
I heard the story of a boy trying to learn how to ice-skate. He had fallen so many times that his face was cut, and the blood and tears ran together. Out of sympathy, a man skated over to the boy, picked him up and said, "Son, why don't you quit before you kill yourself?"
He wiped the tears from his face and told the man, "I didn't buy these skates to learn how to quit; I bought them to learn how to skate."
