Like other drugs many people experiment with in high school, a little won't hurt you but prolonged exposure to Rand can lead to cognitive deficits and antisocial behavior.
I experimented with socialism in High School. I was actually reading authors much more banal than Ayn Rand could ever hope to be - like Karl Marx and Leon Trotsky. Really glad I grew out of that stage.
Gave up half way through Atlas shrugged I'm afraid. I did enjoy how accurately it depicted socialists and social democrats though - as I was reading it I could help but laugh as I've come across people talking like that so often.
