The Four Agreements
Agreement 1: Be Impeccable with Your Word
Speak with integrity. Say only what you mean. Avoid using the word to speak against yourself or gossip about others.
Agreement 2: Don't Take Anything Personally
Nothing others do is because of you. What others say and do is a projection of their own reality.
Agreement 3: Don't Make Assumptions
Find the courage to ask questions and to express what you really want. Communicate clearly to avoid misunderstandings.
Agreement 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.
