An old man once walking by the beach saw a girl throwing something gently in the sea.
He went closer to ask the lady what was she doing.
She said, “The sun is up and the tides are going low. If I don’t help the starfish, they will die.”
The man said, “What difference does it make? There are thousands of them. You can’t save them all. Your efforts will be in vain.”
The girl replied, “Maybe I can’t save them all. But every life I save makes a big difference.”
Moral – Even a single life saved is worth the effort.
