Many of my students and private clients are good writers. They've taken classes to hone their writing, learned to revise, are adept at choosing that perfect word or phrase to make the reader melt.
But there's a lot more to writing--and publishing--a book than just expert wordsmithing. In my classes, I teach the other side of books, the structure, because I've found it harder to learn and practice. It's not taught that much in schools or even MFA programs. Good writing is, but structure is not. But you know my concerns about (obsession with?) structure if you've followed this blog for any amount of time or taken one of my workshops. It just matters so much, if you want to publish in today's market.
