In the bedroom time I have generated thoughts, and then in the studio I take those thoughts and try to shape them into something.

I [drinking coffee] for about an hour, I get dressed and go down in my studio, and that's a different kind of working.

I had a general outline of subjects. The way I start my days is my husband brings me a thermos of coffee up to the bedroom.

Some of it just involved thinking about, for example, the different kinds of science, what chemistry is.

I don't think about it that much, but sometimes I am surprised by that. I sometimes wonder why I didn't turn out to be the kind of picture-book writer who has stuffed animals that go with their books. That would be okay with me.

I don't feel like it's something I invented myself, rather something I absorbed and continue to do.

I'm German, after all.
