I generally have an idea where I want to go, but I don't know how I'm going to get there.

Often they do go back and forth the whole way, and I don't know until the very end what the last line of the book is going to be. That was true here - the very last line of the book was the last thing that happened.

I love when I'm trying to do something I don't know how to do, and it kind of figures itself out along the way. And that means messing up a lot. That means throwing away a lot of drawings.

It's really daunting when you have just spent a lot of time on something to think about tossing it out. But once you've started something better that's working right, then it's pretty easy to let the first one go.

I knew what infinity was. Being a previous art student, I knew about some art concepts.

One of my favorite moments in that book [As Easy as Falling Off the Face of the Earth] was when something happened that I had no idea was going to happen.

In some ways I'm very structured.
