Discourses, "To a Person Who Had Been Changed to a Character of Shamelessness" (§1)

“When you see another man in the possession of power (magistracy), set against this the fact that you have not the want (desire) of power; when you see another rich, see what you possess in place of riches: for if you possess nothing in place of them, you are miserable; but if you have not the want of riches, know that you possess more than this man possesses and what is worth much more.”
