Books are frozen voices, in the same way that musical scores are frozen music. The score is a way of transmitting the music to someone who can play it, releasing it into the air where it can once more be heard. And the black alphabet marks on the page represent words that were once spoken, if only in the writer's head. They lie there inert until a reader comes along and transforms the letters into living sounds. The reader is the musician of the book: each reader may read the same text, just as each violinist plays the same piece, but each interpretation is different.

I'm a person of whim, and easily distracted. I don't like multitasking. When I'm doing one thing, I like to do just that thing.

What I need is perspective. The illusion of depth, created by a frame, the arrangement of shapes on a flat surface. Perspective is necessary. Otherwise there are only two dimensions. Otherwise you live with your face squashed up against a wall, everything a huge foreground, of details, close-ups, hairs, the weave of the bedsheet, the molecules of the face. Your own skin like a map, a diagram of futility, criscrossed with tiny roads that lead nowhere. Otherwise you live in the moment. Which is not where I want to be.

More and more I feel like a letter—deposited here, collected there. But a letter addressed to no one.

In theory I can do almost anything; certainly I have been told how. In practice I do as little as possible. I pretend to myself that I would be quite happy in a hermit's cave, living on gruel, if someone else would make the gruel. Gruel, like so many other things, is beyond me.

Potential has a shelf life.

When I was 16 I started publishing all kinds of things in school magazines. My main feedback came from my English teacher, Miss Bessie B. Billings, who said, 'I can't understand this at all, dear, so it must be good.
