A Fisherman had no luck. Just before going home a large fish jumped into his boat making his day.
Patience has its own reward.

L’Estrange version
A fisherman had been a long while at work without catching any thing, and so in great trouble and despair, he resolv’d to take up his tackle, and be gone: but in that very instant a great fish leapt into the boat, and by this providence he made a tolerable day on’t.
Moral
Patience, constancy, and perseverance, in an honest cause and duty, can never faile of a happy end, one way or other.
