I haven't written anything yet that makes me think, This is it! and I don't imagine I ever will. I don't know how it is with you, but when I finish something, even when I'm pleased with the results, it never quite matches the shimmering vision that was out ahead of me as I wrote.

The trajectory of my writing has moved further and further away from autobiography. My first stories in Confessions of a Falling Woman worked familiar territory - places I had lived, people I knew, my life as an actor in New York - and many were prompted by or grounded in personal experience.

I think I was also afraid of the novel. I write line by line, proceeding at snail's pace, rewriting as I go and paring the excess away. This is against all the best advice for writing long form prose, and I have tried over the years to break myself of the habit, but I can't bear to leave anything ungainly on the page and half the fun for me is that tinkering. So the length of a novel was a daunting prospect.

I tell my students, if you're interested in marine biology or llama farming, follow that string. Yes, it will probably take you a longer time to write that book, but it's not a race. That's another great thing about being a writer: you don't age out.

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.

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.

Practicality continues to be a challenge for me - it's at odds with being an artist. I actually had a career on stage in New York - not a brilliant career or I'd still be doing it - but I got enough work to keep my agent and my union health insurance.
