In my early work I didn't use much colour. I had no confidence about how I could do this.

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

Usually people start with painting and then go on to make installations; my painting came from installation.

In the studio, it took me a long time to work out how to make paintings that had the intensity that I was able to create by painting whole rooms. There is a very limited number of colours but there are many variations. I decided to use the purest palette that I could.

Today, in British education, we don't have that kind of freedom. Now there are many regulations, many rules, and bureaucracies in the education system. So, it doesn't have the flexibility that it had in the '60s, '70s, '80s.

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.

'Understanding' art is like having a sense of humour - if you don't have one, no amount of explanation is going to make you laugh.
