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. ~ Emerson
That's why I love this quote. It's a gentle reminder that as long as you do your best with what you've been given you can feel at ease when you finish, no matter what did or didn't get crossed off your list.
