There is an old story that tells of a man walking along a beach when up ahead in the distance, he catches sight of another man acting strangely. As he gets closer, he notices the man is picking things up from the sand and throwing them into the water.
Upon reaching him, he sees the objects being tossed are starfish, stranded on shore by the retreating tide. Curious about his intentions, the first man asked, “What are you doing?”
“I am saving these starfish,” he replied. “They won’t survive in the sun until the tide returns.”
Totally taken aback by this statement, the first man said, rather indignantly, “Aren’t you being a little silly? Do you not realize how many hundreds of thousands, perhaps millions, of starfish there are in the sea and that by throwing a few back will make absolutely no difference at all?”
The second man said nothing but was unfazed. He picked up yet another starfish and threw it out into the waves. He hesitated for a moment, then looked back the first man and said, “I just made a difference for that one.”
