As
I have no problem with people who say, "Here's how I do it. It works for me, why not give it a try?" (John Braine does that in his How to Write a Novel, which as it happens is the total opposite of Butcher's Plan Everything Up Front method.) But those who say, "This is how you must do it," are dangerous to new writers. To be fair, Butcher does give a small disclaimer at the very beginning, but it's overwhelmed by the rigid instructions that follow.
So my writing revelation for the week had been "Trust Your Gut!" which is completely the opposite to Butcher's advice. :)
Having said that, and just to show that there are little lessons and bits of useful information that can be found in even the crappiest of crap advice if you cherry pick, the bit about the Big Middle was reassuring. Because in the very very original version of the WIP (back when I was about 15 and it was called The Land Beyond the sea), the big battle was the climax that came at the end. More recently it's been moved to the middle and has never felt comfortable there, but now Butcher has said that it's acceptable to have a big climax in the middle, I feel much happier about it and feeling happier will help me get a better grip on how to structure the novel.
