My freshman English professor at Kent State University in 1984 told me I was a good writer, and she loved all the silly pictures I drew in my notebook. She said I should try writing children's books, and so I did.

Encourage kids to be creative without worrying about being perfect.

Try to remember that being unsuccessful in school doesn't automatically mean you'll be unsuccessful in life. Lots of people who didn't excel in school still went on to have successful lives.

My goal with The Adventures of Captain Underpants was to invent a style which was almost identical to that of a picture book - in a novel format. So I wrote incredibly short chapters and tried to fill each page with more pictures than words. I wanted to create a book that kids who don't like to read would want to read.

Nothing prevents boredom like a good book.

I think if you can show a kid that reading can actually be fun, it can make you laugh, inspire imagination - that can make a huge difference, that can help a child who's struggling with reading to really look at it differently.

Grown-ups do a lot of complaining!
