The Fisherman & the Little Fish
"Please spare me, Mr. Fisherman! I am so small it is not worth while to carry me home. When I am bigger, I shall make you a much better meal."
But the Fisherman quickly put the fish into his basket.
"How foolish I should be," he said, "to throw you back. However small you may be, you are better than nothing at all."
A small gain is worth more than a large promise.
