I've learned at the book signings that everyone has obstacles.

I've had people turn up to book signings with knives, with guns.

I've loved traveling around the country and meeting people at book signings.

I meet people at book signings. My record now, for signing, is ten and a half hours in one sitting.

I meet people on the street or at book signings and they tend to treat me as if they know me, as if we're connected. It's great.

If it's one thing we learned from the first book, it's that you don't have to be a prizefighter, or a world-renowned architect, or a concert violinist to have been affected by the power of words.
