I'm fascinated by what makes up a self, how one becomes a self, how much is it an answer to others and how much is it an essence of self. We learn how to be people from other people. Then you think - what's personal freedom? Is self-creation possible? This book is dedicated to a friend of mine who really did re-create herself. I didn't do that - I stayed in the circus and am a circus performer like my parents were. I did what I was raised to do - I'm glad I did but I'm fascinated by the people who managed to do something else. I was always very curious about other people.

I was trained to look at colour, edges, to see negative space. I honestly think my greatest influence as a writer is from Cubism - the idea of a multi-faceted, multi-perspective way of looking at things.

I was 100 percent sure when I left university that I was going to be a painter.

One of the things that's good for me is that I can go from one art form to another.

That's one thing I find about having children - it does unlock a door that separates you from other women who've had children.

I think it's very important to keep being frightened - if you're not frightening yourself, you should take a break. You need to keep experimenting. You also need to take time - that's how you do good stuff - layering and depth of knowledge.

I would have started writing a lot earlier if I hadn't been [Arthur Miller's daughter].
