The only Rand book I ever read was Atlas Shrugged, which I finished mainly out of spite, hurling it into corners and stalking out of the room every few chapters. Wow, she sure liked her ideas. Like, a lot. And she was not so fond of people.
The slogan "Mediocrity despises excellence and hates success" is ironic given that Rand was a relatively mediocre 20th century sociopath with lots of unpleasant things to say about more successful sociopaths like Lenin.
