I have a quote by Ralph Waldo Emerson by my bed that helps me silence my mind: ‘Finish every day, and be done with it. . . . You have done what you could—some blunders and absurdities no doubt crept in, forget them as fast as you can, tomorrow is a new day. You shall begin it well and serenely, and with too high a spirit to be encumbered with your old nonsense.
