Don’t interfere with something that ain’t bothering you none.

Don’t let the bastards grind you down.

Don’t bypass a town where there’s a friend.

Don’t make a mountain out of a molehill.

If you want your dreams to come true, don’t sleep.

Don’t make waves.

Don’t paint the lily.

Don’t plant more garden than your wife can care for.

Don’t put all your eggs in one basket.

Don’t put new wine into old bottles.
