It describes four simple agreements you can make with yourself, which allow you to increase your control over how you live your life: 1) Be blameless with your word; 2) Don`t take anything personally; 3) Don`t make assumptions; 4) Always do your best. It doesn`t mean simple! Don Miguel`s book helps the reader to have the power of these agreements and to use them. Reading Peter Coyotes is a pleasure that supports the learning process. It is a timeless work that can be constantly referred to. I found the four chords even more powerful than Stephen Covey`s seven customs, which was not the case. And just like the Seven Habits, the Four Chords are powerful in every aspect of your life, including family, work, and leisure. Our personal power is based on the agreements we make and we often make those deals to please others instead of being true to ourselves. In doing so, we surrender our personal strength. The four chords aim to regain our personal power by being authentic and clinging to our true self. The four chords are: 1) Be blameless in your word, 2) Don`t take anything personally, 3) don`t make assumptions, and 4) keep doing your best. These agreements are simple, but far from simple. Ruiz encourages readers to practice these chords every day and forgive us if we are not perfect.
