This is a popular anecdote I read somewhere on the net, and thought would share for the benefit of those who haven't seen it.
While walking along a beach, a young gentleman saw an elderly man in the distance, leaning down. On coming closer, the young man saw that the elderly gentleman was picking up starfish painstakingly- one after the other- and throwing them back into the sea.
The young man, consumed with curiosity at this strange behavior, came closer still and called out, “Good morning, sir! May I ask what your grand plan is?”
The elderly man paused, looked up, and smiled, “Simple…throwing starfish back into the ocean.”
The tide had thrown up several thousands of starfish-struggling to breathe -on to the shore.
The young man smiled and asked again, “There are so many thousands of them…you can’t obviously save all of them. So what difference does it make, my good sir?”
The elderly smiled again, and tossing yet another fish into the ocean, remarked, “There! I made a difference to that one.”
