“Finish every 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; begin it well and serenely and with too high a spirit to be cumbered with your old nonsense. This day is all that is good and fair. It is too dear, with its hopes and invitations, to waste a moment on the yesterdays” - Ralph Waldo Emerson

and

“We should all be concerned about the future because we will all have to spend the rest of our lives there” - Charles F. Kettering
