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

When I was a very young student I loved and admired the work of Sam Beckett, who is famously pessimistic, and whose writing is an extraordinary examination of emptiness. I wanted to be like Beckett. I don't have the same attitude toward the world, I'm naturally optimistic, and so of course I could never be like Beckett. You can't force yourself to become like someone you admire.

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.

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.

You can't honour someone by copying them or trying to be exactly like them.

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 had been doing wall drawings, but they were always black and white. Then in 1993 I painted all the walls of a room to make an installation and as soon as I saw the colour on the walls, it changed my whole life.
