How did Atlas Shrugged change your way of thinking? I've read The Fountainhead, but felt like Officer Barbrady when I started Atlas Shrugged many years ago. Maybe it's worth another shot?
While I'm not the OP, I'll answer anyway. It changed how I thought about Atlas Shrugged; previously, I thought it was some kind of political tract cum morality tale, but after reading it I thought it was a fairy tale and was slightly concerned at how seriously it was taken.
