The Starfish :

An old man was walking along the beach, when he came upon a part of the sand where thousands of starfish had washed ashore. A little further down the beach he saw a young woman, who was picking up the starfish one at a time and tossing them back into the ocean. "Oh you silly girl," he exclaimed. "You can't possibly save all of these starfish. There's too many." The woman smiled and said, "I know. But I can save this one, " and she tossed another into the ocean, "and this one", toss, "and this one..." - adapted from a poem written by Randy Poole called The Difference He Made.
