Once I had started, I discovered the secret pleasure of writing a novel. It's such an immersive, deep commitment. With short stories, you're continually having to start again from scratch, but with a novel you only need one good idea every few years.

That requires quite an imaginative leap because it's hard for me to imagine that my biography would be of much interest to anyone, and because I'm a fairly private person, the notion doesn't appeal to me.

I loved short stories, and they were all I wanted to write. I love the compression of them and the exactitude needed to get a whole world into such a small space.

When I left the theatre and turned to writing, one of the big pulls was that, unlike the theatre, I didn't have to wait to be hired before I could do my art. That was huge. But you still have to figure out how to support your habit; it's rare and lucky when art pays the bills.

I always think, OK, this is good, but I'll do it better next time. "And so we beat on, boats against the current. . ." It may not be the recipe for a life of contentment, but that imperfectability is what makes writing such an engaging endeavor, something you can do for the rest of your life and not get bored.

With the historical fictions, I was already doing so much research, and so much of the stories was anchored by historical truth that the move to nonfiction didn't feel all that dramatic - just another half-step to the right.

As a writer, the ideal job is the one that allows you time and mental space away from it. Teaching seemed to me like the obvious choice - those summers off, you know - but my experience may serve as a cautionary tale.
