The Four Agreements, by Don Miguel Ruiz, is one of the better books I have read in the past year and highly suggest it to anyone wanting to deepen their understanding of themselves and the ones they love!
The Four Agreements is a self-help book and guide to practical freedom. It offers a "code" of conduct based on ancient Toltec wisdom that advocates for freedom from self-limiting beliefs that may cause suffering and limitations in an individual's life.
