The books take a year just to do the drawing. I will travel to a country to do the research and get ideas. Sometimes I don't travel to do research, but mostly I do. It takes a long time, but do I ever get tired of it? Not really. The characters kind of grow and evolve.

My parents would tell us to go outside and play or to do creative stuff, but television was very limited. So we used our own creativity to entertain ourselves. We were out in the woods a lot making huts and playing horses.

I always feel like my book is a success when I see a child reading it, and they have their pointer finger out, and they kind of keep their place as they look all around the page. I've always been impressed by how children are so observant.

I love children because that's a part of my life that was so happy, and I like to remember back to those days where everything is a discovery, and the world is so fresh.

Teachers have to respect the privacy of students' creative life, but at the same time give them a chance to express themselves.

I remember kids used to give me a penny for drawing them a horse. I loved horses, but I couldn't have one, so I would draw a horse for myself. I would make it food and a blanket for it to wear and a place to live.

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.
