A man should always have these two rules in readiness. First, to do only what the reason of your ruling and legislating faculties suggest for the service of man. Second, to change your opinion whenever anyone at hand sets you right and unsettles you in an opinion, but this change of opinion should come only because you are persuaded that something is just or to the public advantage, not because it appears pleasant or increases your reputation.
Marcus AureliusA wrongdoer is often a man who has left something undone, not always one who has done something.
Marcus AureliusThis is the chief thing: be not perturbed, for all things are according to the nature of the universal.
Marcus AureliusOur life is what our thoughts make it. Do every act of your life as if it were your last. In a word, your life is short. You must make the most of the present with the aid of reason and justice. Since it is possible that you may be quitting life this very moment, govern every act and thought accordingly.
Marcus Aurelius
