Never feed the appetite, merely feed the hunger.
Declare every morning: I feel fine, I cannot be discouraged, dismayed, confused, influenced, or in any way affected by mortal mind. No thought, conscious or unconscious, felt or unfelt, known or unknown, no power seen or unseen, can in any way touch me, unless it originates in divine Mind. Mary Baker Eddy
