What now?

"Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt have 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 cumbered with your old nonsense. This day is all that is good and fair. It is too dear, with its hopes and invitations, to waste a moment on yesterdays."

Ralph Waldo Emerson
