Does any of this sound familiar?
Hitler was incredibly lazy. According to his aide Fritz Wiedemann, even when he was in Berlin he wouldn’t get out of bed until after 11 a.m., and wouldn’t do much before lunch other than read what the newspapers had to say about him, the press cuttings being dutifully delivered to him by Dietrich.
He was obsessed with the media and celebrity, and often seems to have viewed himself through that lens. He once described himself as “the greatest actor in Europe,” and wrote to a friend, “I believe my life is the greatest novel in world history.” In many of his personal habits he came across as strange or even childish—he would have regular naps during the day, he would bite his fingernails at the dinner table, and he had a remarkably sweet tooth that led him to eat “prodigious amounts of cake” and “put so many lumps of sugar in his cup that there was hardly any room for the tea.”
He was deeply insecure about his own lack of knowledge, preferring to either ignore information that contradicted his preconceptions, or to lash out at the expertise of others. He hated being laughed at, but enjoyed it when other people were the butt of the joke (he would perform mocking impressions of people he disliked). But he also craved the approval of those he disdained, and his mood would quickly improve if a newspaper wrote something complimentary about him.
Hitler’s personal failings didn’t stop him having an uncanny instinct for political rhetoric that would gain mass appeal, and it turns out you don’t actually need to have a particularly competent or functional government to do terrible things.
