“Greatness needs courage (above all) and willpower, charisma, intelligence and creativity but it also demands characteristics that we often associate with the least admirable people: reckless risk-taking, brutal determination, sexual thrill-seeking, brazen showmanship, obsession close to fixation and something approaching insanity. In other words, the qualities required for greatness and wickedness, for heroism and monstrosity are not too far distant from each other. The Norwegians alone have a word for this: stormannsgalskap – the madness of great men.”
