There was a young man walking down a deserted beach just before dawn. In the distance, he saw a frail old man. As he approached the old man, he saw him picking up stranded starfish and throwing them back into the sea. The young man gazed in wonder as the old man again and again threw the small starfish from the sand to the water. He asked him,  Why do you spend so much energy doing what seems to be a waste of time? The old man explained that the starfish would die if left in the morning sun. There must be thousands of beaches and millions of starfish!  exclaimed the young man. How can your effort make any difference? The old man looked down at the small starfish in his hand, and as he threw it to the safety of the sea, said, It makes a difference to this one.
