The Story of the Starfish
A father and his son were walking along a deserted beach after a particularly high tide had washed up thousands of starfish on to the sand. The boy started picking them up and throwing them back into the water one by one. The father quizzed his son saying "You can't possibly save them all, there are millions, you can't possibly make a difference." The boy smiled, bent down and picked up another starfish and as he threw it back into the sea, he replied, "it made a difference to that one."
