Don't beat around the bush.

Don't believe everything you hear.

Don't bite off more than you can chew.

Don't borrow trouble.

Don't burn your bridges behind you.

Don't carry a grudge.

Don't count your chickens before they catch.

Don't change horses in the middle of the stream.

Don't cry over spilt milk.

Don't dig up old bones.

Don't cut off your nose to Spite your face.

Don't get above your raising.

Don't get too big for your britches.

Don't jump from the frying pan in to the fire.

Don't jump to conclusions.

Don't look for trouble.

Don't make a mountain out of a mole hill.

Don't measure your corn in my half bushel.

Don't push your luck.

Don't ride a good horse to death.

Don't send a boy to do a man's job.

Don't start something you can't finish.

Don't wallow in self pity.
