The Four Agreements

Be Impeccable With Your Word
Speak with  integrity. Say only what you  mean. Avoid using the word t o speak against yourself or to gossip about others. Use the power of your word in the direction of truth and love. 

Don't Take Anything Personally
Nothing others do  is because of you. What  others say and do is a projection of their own reality. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering.

Don't  Make Assumptions
Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness, and drama. With just this one agreement, you can completely transform your life.

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, and you will avoid self-judgment, self-abuse, and regret.
