Strolling on the plateau of life, desperate for the mountain, I never thought that I would get this far. It's only art that has carried me through, given me faith in my own existence. But now I am approaching a point in my life where I desire more.

The soul will always do what it needs to do.

There are things going on in galleries recently that have shocked me. What I'm going to say is really controversial, but what I find the most provocative is the commerciality of art in general. And the fact that a lot of people have forgotten what the meaning of art is and what the intention behind it is.

When I have an exhibition, I usually arrange it so that if people want to, they can spend two hours there. That way, people who like it don't feel cheated when they go. I want them to walk into the exhibition space and look low and at other levels and angles. The same with emotions. I want them to be emotionally manipulated, to come out feeling something. I want them to laugh, smile, feel sad. Even if they feel angry, that's okay.

Because of the amount of press attention, people went to see this dirty bed, as if it was a freak show. But when they got there, they saw something else - the bed, stuff on the walls, whatever. For the Tate, it's the highest attendance they ever received for the Turner Prize show. There was a massive queue, and when you got into my bit, you couldn't move.

Someone else who liked what I did might turn around and say, "She's reworking and rethinking everything. She could just be making blankets now, and be a lot wealthier." I'm actually making it difficult for myself. I wouldn't call it re-branding. If I get bored with my work, then other people will - it's that simple. And I'm not gonna get bored with what I'm doing. I'll struggle and fight and do new things to excite myself - and do it in my own sweet way.

I've worked really hard. I've made three pieces of seminal art in my life. If I died tomorrow, I'd be remembered for making them. There are a lot of artists who, no matter how hard they work in their lives, will never make anything seminal.
