The four agreements are: „The Four Agreements“ not only gave me the four agreements by which I made small positive changes in my life, but the book also helped me understand the process of „Domestication“ and how this „Domestication“ shaped my belief systems. The fourth agreement allows readers to have a better understanding of the progress made in achieving their goals in life. This agreement involves the integration of the first three agreements into daily life and the exploitation of its own potential.  It is a matter of doing the best that can be managed individually, which varies from the different situations and circumstances that the individual may encounter. Ruiz believes that if you judge yourself and do your best at all times, you will be able to avoid remorse.  By integrating the first three chords and doing the best in all facets of life, the individual will be able to lead a life without grief or self-awareness.  In the first part of this two-part video, we learn how the „domestication“ of men and how all the rules and values of our family and society are imposed on us by a system of punishment and reward. As young children, our true nature is to love and be happy, to explore and enjoy life; We are absolutely authentic.
But then we learn to be what others think we should, and because it`s not normal that we are who we are, we start pretending we`re not what we`re not. When we are teenagers, we have learned to judge ourselves, to punish ourselves and to reward ourselves after agreements that we have never chosen. The four agreements help us break self-limitation agreements and replace them with agreements that bring us freedom, happiness and love. The four agreements© were published in 1997 and have sold about 9 million times. He has been on the New York Times bestseller list for nearly a decade. Everything we do is based on agreements we have made – agreements with ourselves, with other people, with God, with life. But the most important agreements are those we make with ourselves.
