Every hour be firmly resolved… to accomplish the work at hand with fitting and unaffected dignity, goodwill, freedom, justice. Banish from your thoughts all other considerations. This is possible if you perform each act as if it were your last, rejecting every frivolous distraction, every denial of the rule of reason, every pretentious gesture, vain show, and whining complaint against the decrees of fate. Do you see what little is required of a man to live a well-tempered and god-fearing life? Obey these precepts, and the gods will ask nothing more (II.5).

Your days are numbered. Use them to throw open the windows of your soul to the sun. If you do not, the sun will soon set, and you with it. (II.4)
