I write about what I know; and I write about things that are new to me, and that I didn't know before.
I write articles, and I do profiles of members of organizations and associations.
That's what sons do: write to their mothers about recall, tell themselves about the past until they come to realize that they are the past.
Ultimately, you can only ever write what you know. It's logically and philosophically impossible to write what you don't know.
If you have a structure beforehand, you're sort of stuffing your story into a pre-assembled box. You don't want that to happen. What you want in your writing is to have a sort of wildness that occurs. And then, out of the wildness, a structure emerges.
If you sort of see yourself writing into a space that you don't always recognize, you sometimes learn things that you knew, but weren't entirely aware of. It's very liberating for a writer to go into a space where she or he has not gone before, because, instead of being a tourist, you're like an explorer now, and you're sort of lost in this new idea.
I'm not so sure that I can teach people how to, you know, write dialogue or create plot or anything like that. But if I can get them and grab them by the scruff of the neck and say, you can do this, and if I see that fire in their eyes, that's when I think I know a writer.
Personally, I like the social novel. I like writing that gets in and under the hood and looks about - at what's going on. But I don't say to any writer that that's absolutely what they should do.
