"A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages. Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty. Trust thyself: every heart vibrates to that iron string."

Ralph Waldo Emerson, Self-Reliance (1841)

Maybe my favorite essay. Certainly my favorite Emerson essay. I hope they still teach it in high school. Encountering Emerson and Thoreau in high school felt life changing.
