Every action, says don Miguel Ruiz, is based on agreements people make - with other people, with God, with life. But the most important agreements are those people make with themselves. In these agreements they tell themselves who they are, how to behave, what is possible, what is impossible. One single agreement is not such a problem, but so many agreements come from fear, deplete energy, and diminish self-worth. In The Four Agreements, don Miguel reveals the source of self-limiting agreements that take away joy and create needless suffering. For those ready to change these agreements, there are four deceptively simple, yet powerful agreements that can be adopted as guiding principles: be impeccable with your word; don't take anything personally; don't make assumptions; and always do your best. These tenets can rapidly transform anyone's life to a new experience of freedom, true happiness, and love.
