Ralph Waldo Emerson
"What lies behind us and what lies before us are tiny matters compared to what lies within us."
"In my walks, every man I meet is my superior in some way, and in that I learn from him."
"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; you shall begin it well and serenely, and with too high a spirit to be cumbered with your old nonsense."
