Cut your coat according to your cloth.
Do as you would be done by.
Do not halloo till you are out of the wood.
Do not spur a willing horse.
Early to bed and early to rise makes a man healthy, wealthy, and wise.
Empty vessels make the greatest sound.
Enough is as good as a feast.
Faint heart never won fair lady.
Fine feathers make fine birds.
Fine words butter no parsnips.
