As far as being territorial about one's own life, that's a mistake for ANY writer. All writers everywhere, in every genre, are drawing from their life and the lives of those around them for "material." Memoirs just make transparent and even amplify that activity.

Which is mightily ironic since one of the most common criticisms of American women novelists (it's a load of crap but it gets bandied about a good bit) is that they don't write the "big" stories about "universal" or "worldly" concepts...Jesus. Um, when we do? We get told to get back in the kitchen and bedroom - go back to writing about love-y wife-y mother-y things.

We can't handle violence in women characters but we CAN handle what's done to women in our present tense every second of the day worldwide? Or next door? Or in political or medical discourse? Please. That idea just makes me want to crap on a table at a very fancy restaurant.

The maternal impulse in animals to protect their young - that kind of instinct and subsequent violence is quite beautiful. Mythic even.

The practice of employing metaphor and image and composition and linguistic choices to move the reader through the content.

I look for the moment(s) in the story where the writer risked abandoning the glory of the self in favor of the possible relationship with an other. I don't ever let the market tell me what a memoir is. The first best memoir I ever read was Leaves of Grass by Walt Whitman.

Make up stories until you find one you can live with.
