You can be invincible, if you enter into no contest in which it is not in your power to conquer. Take care, then, when you observe a man honored before others or possessed of great power or highly esteemed for any reason, not to suppose him happy, and be not carried away by the appearance. For if the nature of the good is in our power, neither envy nor jealousy will have a place in us. But you yourself will not wish to be a general or senator or consul, but a free man: and there is only one way to this, to despise (care not for) the things which are not in our power.
