The Four Agreements

Ruiz recovers Toltec wisdom and distils it into four agreements for living better: be impeccable with your word, don't take anything personally, don't make assumptions, always do your best. The philosophical framework is popular spirituality rather than rigorous thought, and that limits its reach for critical readers. But the four principles, stripped of their wrapper, contain real practical sense. A book that works better as a reminder than as a revelation.
