As he came closer, he saw thousands of sand dollars the tide had thrown onto the beach. Unable to return to the ocean during low tide, the sand dollars were dying. He observed a young boy picking up the sand dollars one by one and throwing them back into the ocean.
After watching the seemingly futile effort, the observer said, "There must be thousands of sand dollars on this beach. It would be impossible for you to save all of them. There are simply too many. You can't possibly make a difference."
The young boy smiled as he picked up another sand dollar and tossed it back into the ocean. "It made a difference to that one," he replied.
