Once upon a time, a man and his wife had a goose which laid a golden egg every day. It brought them fortune. Lucky as they were, they soon began to think they were not getting rich fast enough.
They imagined that if the bird laid golden eggs, its insides must be made of gold. And they thought that if they could get all that precious metal at once, they would get mighty rich very soon. So the man and his wife decided to kill the bird.
However, upon cutting the goose open, they were shocked to find that its innards were like that of any other goose! So now the bird was dead and unable to lay any more golden eggs.
Moral of the story: Don’t be greedy and appreciate what you have.
