I heard this story today from a friend.
The story takes place on a beach where thousands of starfish have been washed up. The tied is going out, and the sun is coming up.
A young girl is bending down and picking up a starfish, one at a time, and throwing them into the sea.
A perplexed older man enquires, “Why are you doing this, surely you know that you cannot save them all? you cannot begin to make a difference.”
Dejected, the young girl looks sad but after a minute or so, she bends down and picks up another starfish before throwing it back into the sea. She looked up at the older man and said
“I made a difference to that one”.
