“Every time you sit down to work, remind yourself: I am delaying gratification by doing this.  I am passing the marshmallow test.  I am earning what my ambition burns for.  I am making an investment in myself instead of in my ego.  Give yourself a little credit for this choice, but not so much, because you’ve got to get back to the task at hand: practicing, working, improving.” ~ Ryan Holiday, Ego is the Enemy
