I am personally happy for artists to make as much money as they can while they can to carry them through the times when they can't.

It's important for me to give each thing the possibility to speak and also to allow artworks speak to each other.

Often people do not properly value things that they are good at naturally because they find them too easy. That is very problematic.

I was poorer than anyone I'd ever met. But it was a great time to be a young artist - I remember it as a period of exceptional creative freedom and adventure, when one was regularly presented with works of art unlike anything one had ever seen before.

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've taken away everything I could think of, and yet what remains is enough. These days many more people come to my work, and once they see my work they will always recognize it.

Sometimes we look at a work of art and we immediately think that it is German art, but with some we don't, it's not so obvious.
