Renew every day your conversation with God: Do this even in preference to eating. Think more often of God than you breathe.
EpictetusKeep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours.
EpictetusWherever I go it will be well with me, for it was well with me here, not on account of the place, but of my judgments which I shall carry away with me, for no one can deprive me of these; on the contrary, they alone are my property, and cannot be taken away, and to possess them suffices me wherever I am or whatever I do.
