finish every day : and be done with it

“Finish every day and be done with it. You have done what you could; Some blunders and absurdities 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 (Image and quote via the great Quote Vadis blog, check it out.)
