Ralph Waldo Emerson (May 25, 1803 – April 27, 1882) was an American essayist, lecturer, philosopher, and poet who led the transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thoughts through dozens of published essays and more than 1,500 public lectures across the United States.

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little coarse, and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up again, you shall never be so afraid of a tumble.
Finish every day and be done with it. You have done what you could; some blunders and absurdities 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.
