To make anything a habit, do it; to not make it a habit, do not do it; to unmake a habit, do something else in place of it.
EpictetusWhen you let go of your attention for a little while, do not think you may recover it whenever you please.
EpictetusIn a word, neither death, nor exile, nor pain, nor anything of this kind is the real cause of our doing or not doing any action, but our inward opinions and principles.
