A poor fisherman, who lived on the fish he caught, had bad luck one day and caught nothing but a very small fry. The fisherman was about to put it in his basket when the little fish said:"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.
