“Write it on your heart

that every day is the best day in the year.

He is rich who owns the day, and no one owns the day

who allows it to be invaded with fret and anxiety.

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, with too high a spirit

to be cumbered with your old nonsense.

This new day is too dear,

with its hopes and invitations,

to waste a moment on the yesterdays.”

An American essayist, poet, and popular philosopher, Ralph Waldo Emerson (1803–82) began his career as a Unitarian minister in Boston, but achieved worldwide fame as a lecturer and the author of such essays as “Self-Reliance,” “History,” “The Over-Soul,” and “Fate.” Drawing on English and German Romanticism, Neoplatonism, Kantianism, and Hinduism, Emerson developed a metaphysics of process, an epistemology of moods, and an “existentialist” ethics of self-improvement. He influenced generations of Americans, from his friend Henry David Thoreau to John Dewey, and in Europe, Friedrich Nietzsche, who takes up such Emersonian themes as power, fate, the uses of poetry and history, and the critique of Christianity.
