Discourses: Book 3 24 : 19
If you have these thoughts always at hand and go over them again and again in your own mind, and keep them in readiness, you will never need a person to console you, or strengthen you. For disgrace does not consist in not having anything to eat, but in not having reason sufficient to secure you against fear and against grief. But if once you win for yourself security against grief and fear, will there any longer exist for you a tyrant, or a guardsman, or members of Caesar's household; or will some appointment to office sting you with envy, or those who perform sacrifices on the Capitol in taking the auspices, you who have received so important an office from Zeus? Only make no display of your office, and do not boast about it; but prove it by your conduct; and if no one perceives that you have it, be content to live in health and happiness yourself.
