“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
There’s nothing more refreshing than starting anew, my friend. And you know, all it takes is you making the decision to do so.
Just let the past be the past. “Now what?” is all you ever need to focus on.
