“Happiness is for children and animals, it doesn’t have any biological function. Happy people don’t create anything, their world is one without art and music and skyscrapers, without discoveries and innovations. All leaders, all of your heroes, they’ve been obsessed. Happy people don’t get obsessed, they don’t devote their lives to curing illnesses or making planes take off. The happy leave nothing behind. They live for the sake of living, they’re only on earth as consumers. Not me.”
