"THOROUGHLY worldly people never understand even the world; they rely altogether on a few cynical maxims which are not true. Once I remember walking with a prosperous publisher, who made a remark which I had often heard before; it is, indeed, almost a motto of the modern world. Yet I had heard it once too often, and I saw suddenly that there was nothing in it. The publisher said of somebody, 'That man will get on; he believes in himself.' And I remember that as I lifted my head to listen, my eye caught an omnibus on which was written 'Hanwell.' I said to him, 'Shall I tell you where the men are who believe most in themselves? For I can tell you. I know of men who believe in themselves more colossally than Napoleon or Caesar. I know where flames the fixed star of certainty and success. I can guide you to the thrones of the Super-men. The men who really believe in themselves are all in lunatic asylums.' "
~G.K. Chesterton: from Orthodoxy, II.―The Maniac.
