One day a man was walking along the beach when he noticed a figure in the distance.  As he got closer, he realized the figure was that of a little boy picking up something and gently throwing it into the ocean.  Approaching the boy he asked, "what are you doing?"   The youth replied, "Throwing starfish into the ocean.  The sun is up and the tide is going out."

"Son," the man said, "Don't you realize there are miles and miles of beach and hundreds of starfish?   You can't possibly make a difference."  After listening politely, the boy bent down, picked up another starfish and threw it into the surf.

Then smiling at the man, he said,  "I made a difference for that one."
