Writing a song is a long road. Or it can be.

It's not often I get to do a film that turns out good. Plus, there just aren't that many great directors out there. There are a thousand different decisions that need to be made with each script and it's the good directors that can make those decisions. It's a long and complicated process in regards to what looks good on paper. Working on a bad film can be fun too. It can be a good exercise that gets you writing.

I don't pretend to understand him, but I can enjoy him as a poet and comedian. I liked the idea of the eternal return. Sometimes I think that being on tour year after year is an eternal return; you play a certain club in Copenhagen and then ten years later you are back again, traveling the same roads year after year.

Don't be a rock star. I've seen people around me have their lives destroyed by drugs. It just depends on what kind of person you are. Like, some people have a "go" button and a "stop" button, and some people just have the "go" button, meaning that they take drugs and just take more, and more, and more. It could be 6 in the morning and they'll say, "Okay, I have to get more now." I'm not that kind of person.

It's weird being an author because it's different than writing songs. You put so much more of yourself out there to be judged because it's a memoir. So when the reviews come in, they all feel really personal. Some people are just going to hate you no matter what. Personally, I never believe good reviews. When people tell me they love the book, I just shrug and say, "Yeah, whatever." My shrink says it's all about the love within. You have to love yourself or you'll never be able to accept compliments from anyone.

I guess I could be singing about Superman, or about Zarathustra coming down from the mountain, but in my mind I was singing about Julian Assange. I wish I could say that Nietzsche inspired my lyrics but all I can honestly say is I was inspired by the graphic design of these '70s paperback covers for Beyond Good & Evil and The Birth of Tragedy and The Gay Science.

They didn't teach Nietzsche in the philosophy department at Harvard; philosophy there was strictly analytical stuff and the poetic ramblings of Nietzsche did not belong. And see - you are teaching it in a literature class - so they must have been right.
