We can use the fourth chord, Do Your Best, to encourage us to aspire positively. But this agreement also recognizes that “our best” varies from moment to moment, depending on our circumstances and mental state. Recognition of this fact leads to the realization that everything we are doing right now is of our best, and this awareness can prevent us from flogging ourselves if we are not up to an unreasonable standard of perfection. The fourth agreement allows readers to better understand the progress made in achieving their life goals. This agreement implies the integration of the first three agreements into daily life and the full potential of exploitation.  It`s about doing what`s best to manage individually, which is different from the different situations and circumstances the individual may face. Ruiz believes that if you avoid self-judgment and do his best at every given moment, he will be able to avoid regrets.  By integrating the first three chords and giving the best of themselves in all facets of life, the individual will be able to lead a life free of sadness and self-extinction.  I also found it strange to judge a book based on the behavior of a person who claims to have read it and the elderly people who are the ancestors of the author of the book. For this reason, I did not respond to Cccc`s comment. If the commentator explained why he thinks the four agreements encourage people to behave ruthlessly and selfishly, I might have had an answer. .
