“Ask yourself the following first thing in the morning: What am I lacking in attaining freedom from passion? What for tranquillity? 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
