“I’m not the smartest guy in the world, but I’m certainly not the dumbest. I mean, I’ve read books like "The Unbearable Lightness of Being" and "Love in the Time of Cholera", and I think I’ve understood them. They’re about girls, right? Just kidding. But I have to say my all-time favorite book is Johnny Cash’s autobiography "Cash" by Johnny Cash.”
― Nick Hornby, High Fidelity
