First of all, to do performance art, you really have to give 100 percent. I only know that I have to give 100 percent and then what happens, happens.

Performance has to be mainstream art. This is what I'm fighting for.

From the very early stage when I started doing performance art in the '70s, the general attitude - not just me, but also my colleagues - was that there should not be any documentation, that the performance itself is artwork and there should be no documentation.

Performance is there, and if you are not there in that moment it happened, it just stays in the memory. It's so immaterial and something this immaterial is very difficult to collect. Its difficult to buy, its how we can buy immaterial art.

I really don't like art where you need to know so much theory to understand. If the theory is removed, it doesn't do anything. That means that this work is an illustration of theory, and I don't believe in the power of the work itself.

I really think there's no difference between an art piece made by a man and one made by a woman. Is it a good art piece or a bad art piece? Of course, if you're female, you're maybe dealing with different issues.
