I think that ideas like First Draft are great for beginners, first-time novel attemptees and that kind of thing. They are brilliant for getting people into the habit of writing. I think they fall down when you're already writing by habit, and when you've got several novel-length works under your belt.

Ultimately, creativity doesn't lend itself to efficiency - and you've got the only thing that can sustain a professional writing career, a two-book contract with a major publisher.
