Marilynne Robinson is one of few writers I’d love (well, more accurately, consent) to take a class with:
I try to make writers actually see what they have written, where the strength is. Usually in fiction there’s something that leaps out—an image or a moment that is strong enough to center the story. If they can see it, they can exploit it, enhance it, and build a fiction that is subtle and new. I don’t try to teach technique, because frankly most technical problems go away when a writer realizes where the life of a story lies. I don’t see any reason in fine-tuning something that’s essentially not going anywhere anyway. What they have to do first is interact in a serious way with what they’re putting on a page. When people are fully engaged with what they’re writing, a striking change occurs, a discipline of language and imagination.
