People may think that because I have illustrated and written all these books it must be easy for me, but it's not really easy for me. The drawing part is easy - I love doing it. But continuing to move forward is hard.

A lot of times it's the child that sees something and not the grownup. I love that because, when readers get older, they start looking for the most important ideas in the story. They don't look at things in the same way anymore. Children haven't really learned to do that yet. They take all their great, intellectual skills, look at the full page, and appreciate all of the different things.

When I go to another country, I try to be a big sponge and look at what the houses may look like and what colors predominate. I do not do research as much as just get ideas and ask people about things.

When I was little I used to wish I could talk to the illustrators because I wanted to discuss something about the books. With so many of the other art forms that children experience, such as movies and television, they don't get to control the pace.

Writing a story is like going down a path in the woods. You follow the path. You don't worry about getting lost. You just go.

I like to pretend that each book is my first one and last one, because it takes a tremendous amount of energy to do a book.

I knew that I wanted to be an illustrator since I was in kindergarten. I can remember the exact day. The art teacher usually came to our classroom once a week, but she was absent that day. Instead, our regular teacher gave us each a huge piece of paper and crayons, and we could do whatever we wanted.
