The Boy and the Starfish

Once upon a time, a man walking along a beach saw a boy picking up starfish and throwing them into the sea.

He asked the boy why he was throwing starfish into the sea.

The boy replied, "The tide is going out. If I don't throw them in, they'll dry up and die."

The man smiled patronisingly and said, "But, there are miles of beach and thousands of starfish on every mile. You can't possibly make a difference!"

The boy smiled, bent down, picked up another starfish, and threw it into the sea.

"Well," he said, "I made a difference for that one."
