“Never do anything wrong to make a friend or keep one”

“Love all, trust a few,
Do wrong to none: be able for thine enemy
Rather in power than use; and keep thy friend
Under thy own life's key: be check'd for silence,
But never tax'd for speech.”

“Never let anyone shame you into doing anything you don't choose to do. Keep your identity.”

“Now, my mom always said two wrongs don't make a right. But she never said anything about four wrongs, and that always left me confused.”

“How to make friends and keep them.”

“Mistress, I have never asked anything of you in my servitude. But now, I beg you this: do not make me keep passing these adolescent sentiments back and forth all night.”

“Neither make thy friend equal to a brother; but if thou shalt have made him so, be not the first to do him wrong.”

“If you want to keep a friend, never test him.”

“The best of the diviner breed are never wrong because they never set anything in stone.”

“I hate doctors! They'll do anything — anything to keep you coming to them. They'll sell their souls! What's worse, they'll sell yours, and you never know it till one day you find yourself in hell!”
