This is the first lesson for writers - or anyone - who conducts interviews: If you want someone to talk, you've got to know how to listen. And good listening is a surprisingly active process. The interviewee is your focus of attention; you are there to hear what he says and thinks, exclusively.
The biggest lesson that I've learned is that fashion is this tightrope where you have to be consistent but inconsistent. You need the connective thread but at the same time you need a sense of surprise.
Sometimes kids ask how I've been able to write so many books. The answer is simple: one word at a time. Which is another good lesson, I think. You don't have to do everything at once. You don't have to know how every story is going to end. You just have to take that next step, look for that next idea, write that next word.
That's an important lesson for me, to not qualify my experience against somebody else's. My experience is the experience that I wanted to have, and have created for myself, but it doesn't make me any more deserving than anybody else - or less.
Sometimes a little heartbreak is a lesson, and the best thing to do is just learn the lesson.
