Writing is the thing that pervades my whole day - I'm always wondering how I might describe something or improve my understanding. I'm constantly trying to remember an eavesdropped conversation or an idea for a story.

I have a study at the back of the house, overlooking our garden. It's tiny, just wide enough to fit my desk in. The walls are covered with pin boards and art postcards from galleries all over the world, including Tate, MoMA, and Lenbachhaus.

When you are in the midst of writing a book, I think it is important to touch base every day. If I wasn't writing something, I would be reading back what I'd already written. I did take a month off writing at one point and found it really difficult to get back into the world I'd created.

I'm not a writer who thinks about writing only for themselves; I do always have a reader in mind.

As opposed to putting too much confidence in myself, or in an image or a scene or a set of brushes, I really want to allow the oil paint to perform, to show me the things that it wants to do, beyond my imagination.

The writing is the springboard for your intuitive stuff and then you see, maybe a colour of what you want to achieve. Then you bring in the technique you've learnt. But when you're on film, you're not always in control of that. That's what makes me believe in a kind of collective unconscious, a sort of experience you draw on.

Creativity, for a lot of young people, is a coping mechanism. It's the only place they feel comfortable. It's the only time they feel like they're being heard or can make a difference, is if they can go into a room and do a drawing or go to a garage and play a song or retreat to this world.

There just is exponentially more money in the movie business than in the music business. As a result there are more people involved in the creative process.
