Starfish...

An old man walked along the beach throwing starfish that had been stranded by the outgoing tide back in to the ocean. There were hundreds of them to return to the water and obviously he couldn't begin to accomplish the task completely. A cynical young person came along and asked in a most arrogant manner, "What possible difference do you think you can make for all those starfish?" The old man stooped down, picked up another one, ans as he tossed it in to the water, her replied in a quiet, confident tone, "For this one, it makes all the difference in the world."
