If I did not love the things that I do, how could I spend my life doing this? You have to invest what you spend your life doing with pleasure.

The identifying personal association with objects, which are not personal, is an important modern experience - our real association, the strands of our feelings about the objects that surround us. It's also because they are so familiar, we don't think of them as important in the world, but actually they are the world. We are living in a very material world.

You can see in my paintings, I've taken away the context, I've taken away the shadows, I've taken away expression, I've taken away the personal, and yet so much remains!

I have been using the computer as a work aid since the mid-90's. It is extraordinarily well suited to how I think and work and has transformed my practice. Nearly everything I have done in the past 15 years would have been impossible without it. I use the computer for drawing, composing and colour planning everything, from postage stamps to paintings to architectural-scale installations.

The first exhibition that I used bright colours in painting the room was at a gallery in Paris, and there were seven rooms in the gallery. It was very nice gallery, not very big rooms, around the courtyard, it was a very French space. So I painted each room in different colour. When people came to the exhibition, I saw they came with a smile. Everybody smiles - this is something I never saw in my work before.

It's just that some things more important for this and less important for that, and this is true regardless the style of the art.

There was something really wonderful about being able to feel confident about doing my first exhibition in China, that people would have no trouble recognising the images and understanding my work. I also have a lot of freedom in the way I use colour, and I think that kind of freedom in colour is also understandable in every culture.
