Ask yourself the following first thing in the morning :What am I lacking in attaining freedom from passion? :What for tranquility? :What am I? A mere body, estate-holder, or reputation? None of these things. :What then? A rational being. :What then is demanded of me? Meditate on your actions. :How did I steer away from serenity? :What did I do that was unfriendly, unsocial, or uncaring? :What did I fail to do in all these things?
—Epictetus, Discourses, 4.6.34-35
