Writing novels is largely about endurance and patience. I take a lot of breaks, hit walls, and go do something else while I think things through. But I do it every day, and I try to treat it as a job, something that is not dictated by whimsy or muses.

In Holland, we have a saying: 'A knife cuts on two sides.' With the rubber duck, I'm trying to show people what they haven't been seeing in their public space. When the rubber duck is there and when it's gone, you know.

I don't think fashion has to change every five minutes. I'd like these to be clothes you can wear for a long time - ten, 20 years; pass on to your daughter. Why buy vintage when you can open your own closet!
