"We are so well trained that we are our own domesticator. We are an autodomesticated animal. We can now domesticate ourselves according to the same belief system we were given, and using the same system of punishment and reward. We punish ourselves when we don't follow the rules according to our belief system; we reward ourselves when we are the "good boy" or "good girl"."
— Miguel Ruiz (The Four Agreements: A Practical Guide to Personal Freedom, A Toltec Wisdom Book)
