 WORD FOR THE DAY

Saturday, Dec. 1

Finish each day and be done with it. You have done what you could. Some blunders and absurdities have 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
