A man was walking along the seashore and saw a small figure repeatedly performing some ritual on the beach. As he approached, he realized it was a young girl picking up starfish stranded by the receding tide and throwing them back into the water. When the man asked why she was doing this, she replied that she wanted the starfish to live and not dry out in the sun. Though the man pointed out there were millions of starfish and her actions couldn't possibly make a difference, the girl simply picked up another starfish and threw it back into the ocean, smiling that she had made a difference for that one.
