Be impeccable with your word. Don't take anything personally. Don't make assumptions. Always do your best. The most important agreements we make and live by are those we make with ourselves. Drawn from Ruiz's hugely successful adaptation of ancient Toltec wisdom for today, this tiny hardcover book has a ribbon bookmark with a 24-carat gold-plated charm, which may be kept on the bookmark or worn on a bracelet or necklace.
