He is rich who owns the day, and no one owns the day who allows it to be invated by worry, fret and anxiety. — Ralph Waldo Emerson. American philosopher (1803–1882)
Finish each day and be done with it. You have done what you could do. 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.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
