You can be miserable before you have a cookie and you can be miserable after you eat a cookie but you can’t be miserable while you are eating a cookie. – Ina Garten

Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day. You shall begin it serenely and with too high a spirit to be encumbered with your old nonsense. – Ralph Waldo Emerson
