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.

If you have some other profession that allows you your evenings or weekends, terrific, stick with that. Having a profession other than writing also has the potential side benefit of providing you with material, something to write about.

One of the nice things about moving from acting to writing is that your work can be in the public eye without having to be in the public eye yourself. I guess that's not completely true. If you're lucky - and I have been - there are book tours and lectures. I don't have stage fright, and I enjoy meeting people, so that's easy and enjoyable, but it's not a constant, and it's not celebrity.

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.

I just can't fathom tweeting, and I'd rather spend my time writing a book than a blog, but I rather grudgingly agreed to a Facebook page. I had a brief, intense romance with Facebook. It's weirdly addictive, but anything that time-sucking is a danger for a writer who writes as slowly as I do. Now I post only occasionally and nothing very confessional. I think I'm carbon dating myself as I speak.

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.

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.
