The Four Agreements by Don Miguel Ruiz
1. Be Impeccable With Your Word: Speak with integrity. Say only what you mean. Avoid using the word to speak against yourself or to gossip about others. Use the power of your word in the direction of truth & love.
2. Don’t Take Anything Personally: Nothing others do is because of you. What others say & do is a projection of their own reality, their own dream. When you are immune to the opinions & actions of others, you won’t be the victim of needless suffering.
3. Don’t Make Assumptions: Find the courage to ask questions & to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness & drama. With just this one agreement, you can completely transform your life.
4. Always Do Your Best: Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best & you will avoid self-judgment, self-abuse & regret.
