In the 1950s that tug-of-war between the expectations of behaving normally and the limitlessness of thinking freely produces some very strange characters.

There are times I wish I didn't have a job, even though I love my job: I get to work with interesting, eccentric colleagues and equally interesting and eccentric subject matter, both of which are rarities. But, naturally, I would treasure having more freedom someday: of time and of movement. Will I always have a full-time job? I don't know. But I do know that I need to spend at least part of my week in an office, with other people.

I'm an indulgent writer - I'm not sure, however, that's something I'm interested in changing. Writing should be indulgent: you should take big risks on the page, you should make big mistakes, you should be excessive at times. I let myself do as a writer what I probably would be less likely to allow as an editor.

My father collected turtles when he was young. My parent's wedding album, there's two pictures of them getting married and the rest are just pictures of turtles. I remember they had Galapagos tortoises that they had somehow imported illegally and a bunch of other turtles too. I like the animals themselves. They're so self-possessed and self-contained and there's something wise and mysterious about them. I also like that they are prehistoric animals.

Witing is essentially interior work, and many writers are interior personalities. Having a job forces you out of the world of your work, and into the one in which you get to observe people. Yes, you can imagine all this, but as a fiction writer, you can never observe enough the rhythms of how humans move through the world. A job demands that you structure your time much more carefully. You learn how to be resourceful, and that in turn provides a certain intensity of focus.

When you don't have to depend upon your creative work for money, you'll never really have to compromise... Knowing that is hugely liberating as well as artistically clarifying... Being practical about where your money comes from means you can be romantic about your writing... I believe that a healthy society is one that supports its artists, but I also know that that privilege, of being only an artist, is afforded to just a small number. Most of us have to find something else - or live a highly disciplined life, which I'm not willing to do.
