His posts among the first two can be summed up as follows: “Be aware of the chords that dictate your reality and have the discipline to change it.” You could get a little more out of his writing, but not much. Unfortunately, its indications do not go far beyond a well-designed “Just do it”. If you like the job or the job you do, you will do your best without even trying. Your work will feel effortless and you will get much better results. This final agreement will help you increase the power of other agreements while stripping yourself of old patterns. We learn how to act and what we should believe and accept as normal. Ruiz says we should ask ourselves why we accept them and live because we have not chosen these rules and agreements. With consciousness and understanding comes forgiveness. I`m sorry for our past and for the persistent “mistakes” we still have in relation to the agreements we still have.
Forgive us for letting ourselves and the people around us suffer because of these illusions. I`m sorry for the suffering that others cause because of their illusions. If you do your best means working hard because you love the task, your work will begin to feel effortless. Thus, the final agreement – always doing your best – will increase the power of all other chords and help you free yourself. The book is based on a series of spiritual beliefs, held by Toltec`s seniors, to help readers transform their lives into a new experience of freedom, happiness and love.  According to the author, everything a man does is based on agreements he has made with himself, with others, with God and with life itself.  In these agreements, we can tell ourselves who they are, how to behave, what is possible and what is impossible.  Some agreements that create individuals may not cause problems, but there are certain arrangements that come from a place of fear and have the power to deplete emotional energy and reduce a person`s self-esteem.  The book states that these self-limiting agreements cause unnecessary suffering.
 Ruiz also believes that to find personal joy, one must get rid of socially imposed and fear-based agreements that can unconsciously influence the individual`s behaviour and thinking.  Another fundamental premise of the book suggests that much of the suffering is created and that most people have the ability to transform themselves and the negative thoughts they have about the situations in their lives.  The author identifies the sources of unhappiness in life and proposes four beneficial agreements that can be concluded with oneself to improve their general state of well-being.
