I felt ten years old and a thousand years old, but I didn't know how to be my own age. I had never felt that way before, but now I feel like that a lot.

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

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

By the time I finished the book [All Alone in the Universe], Robin Roy was saying, "More pictures!"

The morning time is also a time when I look at what I did yesterday. That's often a jumping-off point for today.

It really does feel, partly because of graphic novels kids read, like there's a lot of freedom with how you can use both images and words, because we think in both of those ways.

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.
