Not only in the creative world but also in the sports world. The most successful achievers in sports are people that are really driven and have that spirit of hunger.

I started with wanting to think about witches, about strong women who have special powers - who are often misunderstood. Then I found some beautiful blue fabric, so I made Blue Witches. My creative process is always like that. Organic, text, theme, subtext, each day evolving and trying to make strong, beautiful clothes. It's that simple.

In the '70s, if anything, it was a more interesting time in fashion. It was a time when things were changing, especially in London.

The same spirit runs through everything I do.

The idea was not to make a huge business, because the bigger you get, the more restraints I thought I might get. Number one was to do what I set out to do: make new and interesting things within the size of the business that is possible to do without restraints. The second goal was to do the business in order to achieve the first goal. That's what many people don't understand.

For me, creation can only come out of a certain kind of unhappiness. They say in Japan, this thing like the hungry spirit - the hungry mind - is what gets you going forward.

Every time before a collection, I say, "I don't want it to come out. I want to cancel it. It's not good. I haven't achieved anything."
