A story goes like this.
A man was walking along a deserted beach at sunset. As he walked he
could see a young boy in the distance. As he drew nearer he noticed that
the boy kept bending down, picking something up and throwing it into
the water. Time and again he kept hurling things into the ocean.
As the man approached even closer, he was able to see that the boy was
picking up starfish that had been washed up on the beach and, one at a
time he was throwing them back into the water.
The man asked
the boy what he was doing, the boy replied,"I am throwing these washed
up starfish back into the ocean, or else they will die through lack of
oxygen. "But", said the man, "You can't possibly save them all, there
are thousands on this beach, and this must be happening on hundreds of
beaches along the coast. You can't possibly make a difference." The boy
looked down, frowning for a moment; then bent down to pick up another
starfish, smiling as he threw it back into the sea. He replied,
"I made a huge difference to that one!"
