Rooted in traditional Toltec beliefs, these four agreements are essential steps on the path to personal freedom: -- Be impeccable with your word. Speak with integrity. Say only what you mean. The word is the most powerful tool humans have. -- Don't take anything personally. Self-importance leads people to think they are the center of the universe, causing pain and injustice. -- Don't make assumptions. To avoid frustration and blame, ask what is meant. -- Always do your best. This is the surest way to avoid self-condemnation, though it is important to realize one's best is always changing.
