The experience of being disastrously wrong is salutary; no economist should be denied it, and not many are.

Most editors are failed writers — but so are most writers.

T. S. Eliot (1888-1965) American-British poet, critic, playwright [Thomas Stearns Eliot]
(Attributed) (1946)

Quoted by Robert Geroux, "A Personal Memoir," in Tate, Allen, ed. T. S. Eliot: The Man and his Work (1967) (orig. printed in the Sewanee Review, vol. 74 (1966)): 

I first met T. S. Eliot in 1946, when I was an editor at Harcourt, Brace, under Frank Morley. I was just past thirty, and Eliot was in his late fifties. [...] agreed with the definition that most editors are failed writers, and he replied: `Perhaps, but so are most writers.'

Sometimes given as "Some editors ..." and prefixed with "I suppose most ..." and "I suppose some ..."

But every man is more than just himself; he also represents the unique, the very special and always significant and remarkable point at which the world’s phenomena intersect, only once in this way and never again. That is why every man’s story is important, eternal, sacred; that is why every man, as long as he lives and fulfills the will of nature, is wondrous, and worthy of every consideration.

Herman Hesse (1877-1962)
Demian (1919)

Courage: to bear unflinchingly what heaven sends.

Euripides (485?-406? BC) Greek tragic dramatist
Heracles, l. 1225 [tr. W. Arrowsmith (1956)]

Without the aid of prejudice and custom, I should not be able to find my way across the room; nor know how to conduct myself in any circumstances, nor what to feel in any relation of life.

William Hazlitt (1778-1830) English writer
Men and Manners, “On Prejudice” (1852)
