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.

Writing songs does not get any easier, and that might be because I am harder on myself than I was twenty years ago. Hopefully, as we grow older and change, there are fresh topics, new perspectives, or at least there should be.

I am interested in politics but have stayed away from writing overtly political songs, or message songs, because I find it difficult to discuss politics intelligently in a 4-minute song. But I am finding there are ways to get bits and pieces of political thought across without preaching that the people have the power or we shall not be moved. Of course these sentiments have their place too - I'm not knocking Phil Ochs - but that's a different kind of music, songs to play at rallies, not to achieve a state of bliss.

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.

It's a scary question for a musician or songwriter today - what does the future hold? It is a strange time in the music business too; it feels like we are all in some kind of transitional period, stuck between old technology and new.

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.
