Begin it well and serenely

“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 soon as you can. Tomorrow is a new day; begin it well and serenely, and with too high a spirit to be encumbered with your old nonsense. This new day is too dear, with its hopes and invitations, to waste a moment on the yesterdays.”

-Ralph Waldo Emerson
