I greatly admired him as a teacher I didn't teach the same way as Josef Albers at all.

I think the best approach is not to be too much like the thing that they are referring to, see it as a guide.

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.

I do think I paid a price as an artist, and I am trying to make up for it now - I work six days a week in the studio, and I've never been happier.

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.

I have never understood, for instance, why some people see contemporary art as divided between 'painting' and 'conceptual art', as though this represented a genuine division.

I look at the character of the exhibition and I treat it as I would a painting or an installation. When I did the Summer Exhibition at Royal Academy, I did it exactly as I would when making a new work.
