toiling all day and catching nothing, a Fisherman pulled up a little Fish. The Fish besought him to let him go, for he was small now, but by and by he would grow to be a big fish and so be worth catching. But the Fisherman answered, "No, no, I have you now, it would be foolish for me to let you go; I might not get you when you had grown bigger."

A bird in hand is worth two in the bush.
