Each time I write a new piece, whether a novel, a picture book, a speech or anything, really, it has so much to do with what I'm going through personally or a problem I'm trying to work out. When I wrote my novel 'Baby,' my three children had all just gone out the door.

I have to write what I can write, and writing the text of a picture book is like walking a tightrope, if you ramble off... As my friend Julius Lester says, 'A picture book is the essence of an experience.'

I write the best book that I can write each time.

In a novel, you have space to develop a character or a scene. You don't have that luxury in a 700-800-word picture book.

I had tried writing novels for many years, and they always escaped me. For a long time, I thought, 'It's just not in me to write a novel. It's not something I'm able to do.' It seemed like everything I wrote naturally ended at the bottom of page three. A picture book, three pages; an essay, three pages.

Everyone thinks they're going to write one book of poems or one novel.
