your own thought

“To believe your own thought, to believe that what is true for you in your private heart is true for all men, — that is genius. Speak your latent conviction, and it shall be the universal sense; for the inmost in due time becomes the outmost,—— and our first thought is rendered back to us by the trumpets of the Last Judgment.” ― Ralph Waldo Emerson, Self-Reliance and Other Essays
