When I'm off the road, and I can really control my diet down to the calorie, I juice seven days a week. Every afternoon, whatever I have at hand, beets, carrots, ginger, whatever. I juice, literally, every single day. And on the road, I try to find fresh juice wherever I can.

All my big heroes are literary, writers. I'd love to meet Jimmy Hendrix or John Coltrane, but I'd much rather meet Thomas Wolfe, or F. Scott Fitzgerald. Words and books have always meant a lot to me. That someone can take words and string them together to where they will move me is just a hell of a thing. It's amazing to me; more amazing to me than music or painting. It's always been the written word or the spoken word, like a great lecture or a great lyric, or a great poem. To me it's just amazing. And I always aspire toward capturing that, or my version of it.
