The Four Agreements / by Nathan Jones

They are:

  1. Keep your word impeccable.

  2. Don’t take anything personally.

  3. Make no assumptions.

  4. Always do your best.

Too thin to serve as a moral code, but useful principles, nonetheless. Echoes of Stoicism and Buddhism, and, with regard to the power of the spoken word, Judeo-Christianity. A quick, worthwhile read.
