Finish each day and be done with it. You have done what you could. Some blunders 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
"The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well." -- Ralph Waldo Emerson
