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.” 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.
Little of this was especially secret or unknown at the time. It’s why so many people failed to take Hitler seriously until it was too late, dismissing him as merely a “half-mad rascal” or a “man with a beery vocal organ.” In a sense, they weren’t wrong. In another, much more important sense, they were as wrong as it’s possible to get. Hitler’s personal failings didn’t stop him from 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.
