Refuse.

Men say, Ah! if a man could impart his talent, instead of his performance, what mountains of guineas would be paid! Yes, but in the measure of his absolute veracity he does impart it. When he does not play a part, does not wish to shine,—when he talks to men with the unrestrained frankness which children use with each other, he communicates himself, and not his vanity. All vigor is contagious, and when we see creation we also begin to create. Depth of character, height of genius, can only find nourishment in this soil. The miracles of genius always rest on profound convictions which refuse to be analyzed. Enthusiasm is the leaping lightning, not to be measured by the horse-power of the understanding. Hope never spreads her golden wings but on unfathomable seas. 

Ralph Waldo Emerson, from "Progress of Culture," delivered before the Cambridge University Society of Phi Beta Kappa, 29 August, 1822
