As writers, we must keep throwing problems at our characters. Conflict is the heart of good storytelling. Hiking in nature along a twisting trail can remind us what a good story feels like. It's the opposite of a treadmill - or an interstate highway.

I'm still driven by the feeling I had when I wrote my first book or read a Mrs. Piggle-Wiggle adventure.

One of the best essays I've seen in recent years was by a young woman who wrote about how being chosen to choreograph a high school musical forced her to assume a leadership role she wasn't sure she was ready for - but of course she was.

Early in my publishing career, someone told me I'd need to have five books in print before I could quit my job as a journalist. Turns out it was closer to 10 books. It also turns out that while it's great to see my titles on bookstore shelves, my best customers are schools and libraries.

I took a couple of creative writing classes with Joyce Carol Oates at Princeton University, and in my senior year there, I took a long fiction workshop with Toni Morrison. I fell in love with it.

What I treasure most at any moment is intimacy, surprise, a sense of mystery, wit, depth and love. A handful of cherished friends offer me this, and the occasional singer or film-maker or artist. But my most reliable sources of electricity are Henry David Thoreau, Shakespeare, Melville and Emily Dickinson.

All I can say is, hey, if you have fun doing what you do, if you have fun playing soccer, the creativity is just going to come as time goes on.

Writing was my route to creative expression, and I needed to write about the things that interested me.
