Don Miguel Ruiz's The Mastery of Love and The Four Agreements.

I had been told about the Four Agreements by my good friend Chelsea Stewart, and only got to reading it after first reading The Mastery of Love and feeling inspired to look into other books by Don Miguel Ruiz.  Another amazing friend of mine, Genevieve Harding, had sent me the Mastery of Love for my birthday one year, and it has to go down as one of the best gifts anyone has ever given me.  Both of these books have lasting positive effects on the way I live and interact in this world.  Mastering love and upholding agreements with oneself is a constant effort, so I try to read these books once a year as a reminder of the work to be done.  I hope you too find inspiration and value from these Toltec wisdom books!
