He who angers you conquers you.

Heaven has no rage like love to hatred turned, nor hell a fury like a woman scorned.

Beware of him that is slow to anger for when it is long coming, it is the stronger when it comes, and the longer kept. Abused patience turns to fury.

Never go to bed mad. Stay up and fight.

There are two things a person should never be angry at, what they can help, and what they cannot.
