Having spent the better part of my life trying either to relive the past or experience the future before it arrives, I have come to believe that in between these two extremes is peace. – Author Unknown

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. – Ralph Waldo Emerson

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present. – Marcus Aurelius Antoninus
