I taught up in Maine a couple of times and wasn't able to take a single picture. All that blue sky! Ugh. Sparkling clear air, just terrible. I couldn't do it.

Each time you take a good picture, you have the wonderful feeling of exhilaration... and almost instantly, the flip side. You have this terrible, terrible anxiety that you've just taken your last good picture.

The thing that makes writing so difficult is you don't have the element of serendipity. At least with a photograph, you can set up the camera, and something might happen. You might be a lousy photographer, but you can get a good picture if you just take enough of them.

To be able to take my pictures, I have to look, all the time, at the people and places I care about.

I sell blue sky and coloured air.

I couldn't be Susan Sontag. I'm not very good with abstract thought. I always just take to the emotional core of me.
