What you believe matters, however. It’s all anyone has to act on. And since what you do is who you are, your actions define you. If you don’t believe anything is true simply because you can’t logically prove what’s true, you won’t do anything. You won’t be anything. You’ll end up spending your life in a rocking chair looking out at the horizon waiting for an answer that never comes. You might as well be dead. It’s an old philosophical problem.

One of the things I have tried to do with this book and with all of them really is avoid that simple, easy, reductionist view of motivation and to show we do things for a complex net of reasons, a real braid of reasons.

Storytelling is an ancient and honorable act. An essential role to play in the community or tribe. It's one that I embrace wholeheartedly and have been fortunate enough to be rewarded for.

Although I still occasionally paint and draw, my life has now been shaped by my writing.

I much prefer working with kids whose life could be completely upended by a reading of a book over a weekend. You give them a book to read - they go home and come back a changed person. And that is so much more interesting and exciting.

But really, it was reading that led me to writing. And in particular, reading the American classics like Twain who taught me at an early age that ordinary lives of ordinary people can be made into high art.
