Why isn't Tilda Swinton on the covers of tons of magazines? Well, she's not that. It isn't her thing. But I don't know. I think that suddenly a time came when models, after the Linda Evangelista crowd, and Naomi Campbell and Christy Turlington, when the models for me became a bit bland. But I think more than that, the culture changed. The movies, television, music, and all of those things - those people were more visual and therefore more interesting.

It's true that fashion is looking at fashion all the time, and this is quite boring.

I'm the kind of person who, even after a shoot that I've loved, is always moving on. There is no gap.

Fashion is a playground up until a certain age. But then you have to find your own signature and your own style.

For me, I go somewhere for three days, and then I come back and I want to change everything, and so it's a fight with everybody. I'm transforming and convincing. It's more than designing. It's shaking people and trying to give them direction. I'm a bit of a control freak. This is a problem as I get older, and it's something I should work on. I should be more confident - learn to trust people and give them freedom and delegate.

Strangely, meanness pays more than offering constructive and interesting commentary. Every season I think, "This is the last season. I'm not gonna read tomorrow morning. Forget it." The first thing when I wake up - quite late, usually - I am craving the newspaper.

We live with a future where every three or four months, we have to question everything. You think you could be the best, or that you're nothing and you don't know what you're doing. It is exhausting.
