A Boy was stung by a Nettle.  He ran home and told his Mother, saying, "Although it hurts me very much, I only touched it gently."  "That was just why it stung you," said his Mother.  "The next time you touch a Nettle, grasp it boldly, and it will be soft as silk to your hand, and not in the least hurt you."

Moral: “Whatever you do, do with all your might.”
