Short story with a Moral

One day a fisherman got up very early in the morning.
There was not enough sunlight to get into the sea.

He saw a pack of stones to pass time.
He started throwing the stone into the sea.

While having the last stone in the hand, the sun came up then he saw that the stone was a diamond and all the stones he threw were diamonds as well. He felt for his misfortune of throwing all of them into the sea.

Moral of the story: 

Do not get up early in the morning.
