Book of Proverbs: "A soft answer turns away wrath, but a harsh word stirs up anger."

When anger rises, think of the consequences.

Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned.

If you are patient in one moment of anger, you will escape a hundred days of sorrow.

Spilt water never returns to the tray.

Let go, or be dragged.

The greatest victory is that which requires no battle.
