Unless you're Stephen King or Joyce Carol Oates, no one's going to recognize you on the street, and you're promoting your book, not yourself.

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.

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 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.

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 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.

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.
