There can be no two opinions as to what a highbrow is. He is the man or woman of thoroughbred intelligence who rides his mind at a gallop across country in pursuit of an idea.
Even the greatest fool can accomplish a task if it be after his heart. But the intelligent man is he who can convert every work into one that suits his taste. No work is petty. Everything in this world is like a banyan seed, which, though appearing tiny as a mustard seed, has yet the gigantic banyan tree latent with it. He indeed is intelligent who notices this and succeeds in making all work truly great.

Therefore, in the course of my life I have taught myself whatever I could, and although I am not an educated man, I am able, I am thankful to say, to have an intelligent interest in most things.
Now I'm living out my life in a corner, trying to console myself with the stupid, useless excuse that an intelligent man cannot turn himself into anything, that only a fool can make anything he wants out of himself.
