When I was a teenager, I dreamed of being an opera singer like Maria Callas or a jazz singer like June Christy or Chris Connor, or approaching songs with the kind of mystical lethargy of Billie Holiday, or championing the downtrodden like Lotte Lenya. But I never dreamed of singing in a rock-and-roll band.

My parents had three kids right after the Second World War, and we were all sort of sickly. Then I had a fourth sibling, with very serious asthma. The medical bills... So my parents always struggled.

I always know that everything I do is the best I could do.

You can't make a mistake when you improvise.

We all make choices. Believe me, I would like to write the hit of the world. It's not like I have any desire to be in the shadows. My vision isn't marketing. Some people want to sell 6 million albums. There's nothing wrong with that. It's just not what I do. I'd rather look at a piece of work and say it's great rather than it's successful.

I have abandoned so many projects but in the '80s when I left public life to be married and have real children - I love my children and I would never sacrifice them for anything - I had to find a way to simultaneously be a mother and wife and fulfill my duties and still be true to myself as a writer.

That's what artists do, that's what poets do - we all do it. We start with something, and sometimes we destroy everything that we've made in order to get to the core place where we started from.
