Many people mess up every new day with what happened yesterday. They insist on bringing into today the failures of yesterday, and in so doing pollute a potentially wonderful day. When bitterness, resentment, and revenge are allowed to live in the human heart, words of affirmation will be impossible to speak.
It is useless to meet revenge with revenge; it will heal nothing.
The most miserable prison in the world is the prison we make for ourselves when we refuse to show mercy.
