The mathematics is the odd one, odd because I'm not sure how to measure its effect. It is so fundamental to my outlook on everything and yet I'm not even sure how. It must be because in my formative years it was everything to me, the single place of beauty in my life, and of breathtaking beauty at that. I still believe that pure mathematics is the most creative thing that humanity does, though I am no longer a part of it.

I don't want you to think that I'm being willfully obtuse, but I've never really grasped how point of view could be regarded as a matter of choice independent of story. Point of view is intimately interwoven into the story that you want to tell - it is an aspect of it.

Our interaction with our friends, for instance, is in large part an interaction with representations in our own head of the people before us. That's why a friend can surprise or disappoint us.

Experience belongs to the actor, but the story belongs to the teller. We write so we will never forget.

Novels need readers of a certain kind, people who are patient and enjoy immersing themselves in another perspective for uninterrupted stretches of time. Reading habits might well be changing. People who pay for novels might overlap significantly with those who engage in Twitter and Facebook.

News has a way of distancing us from events, even as it informs us about them. News articles almost always present both the event and the responses at the same time - how is President Barack Obama or Congress responding to the events? I think this reflects a deep need we have to feel that things are under control and that events are subject to our influence.

I am at my happiest when I'm problem solving and a large part of writing is for me a lovely labor in problem solving. Every act of discovery in writing involves a process of figuring out why I'm not seeing what I need to see. Niggling feelings, discomforts, a sense that you've forgotten or overlooked something, a sudden curiosity about what if here? - these are priceless. They are the bases of problems and lead the way.
