Leave well enough alone. If you can't lick them, join them. Sticks and stones will break my bones, but names will never hurt me. Children should be seen and not heard. The fiddle cannot play without the bow.
Good things come in small packages.
A house divided can't stand. Father knows best. One man's loss is another man's gain. For want of a nail the shoe is lost, for want of the shoe the horse is lost, for want of the horse the rider is lost. As the twig is bent, so grows the tree.
