This looks pretty neat. I've always wanted to write but enthusiasm and self-criticism always seems to get in the way. I've gotten several how-to-write books but they don't seem to keep me on track either. Maybe I need a class environment to keep me writing. Signed up and will definitely try to stay on it.
I think one of the cool things about Sanderson's class is that he encourages his students to press on and STOP going back and editing. Meet your writing goal for the week and move on to the next week without constant rewrites. That's smart because it gets you to focus on writing a book even if the book is crap. When you are done with the book you may find that even though it is crap it can be saved in the second draft.
Writing is like programming or any other job that takes a lot of practice to get right. It's best to just sit down and start doing it and don't stop. I'm pretty sure I'd still be thinking
about writing instead of writing if I hadn't taken some writing classes.
