My theory of self-made men is, then, simply this; that they are men of work. Whether or not such men have acquired material, moral or intellectual excellence, honest labor faithfully, steadily and persistently pursued, is the best, if not the only, explanation of their success... All human experience proves over and over again, that any success which comes through meanness, trickery, fraud and dishonour, is but emptiness and will only be a torment to its possessor.
