genius or madness?

“When I was about twelve, I used to think I must be a genius, but nobody’s noticed. Either I’m a genius or I’m mad, which is it? ‘No,’ I said, ‘I can’t be mad because nobody’s put me away; therefore I’m a genius.’ Genius is a form of madness and we’re all that way. But if there’s such a thing as genius – I am one. And if there isn’t, I don’t care.” — John Lennon
