I've started reading Writing From Start To Finish by Kate Grenville, and it's the first 'how to write' book that's ever even remotely clicked with me so now I'm going to bore everyone who reads this thread by talking about it.
The book follows the entire writing process from initially deciding to write something all the way to giving it the final polish. It focuses on short stories and essays, but also explains how the same process can be applied to any kind of writing. Unusually for a writing book, it doesn't start with planning. Or at least, not the plotting/outlining type of planning. Instead, the fiction-writing section starts with the idea of giving yourself an assignment. For example, "Write a novel about a necromancer, using the theme 'serenade of self-destruction'" would be a description of the 'assignment' for my current main writing project. Then you use the directions and constraints of the assignment as the first steps into generating piles of ideas and information - just sort of wild brainstorming at this stage using various combinations of mind-maps, lists, research, and freewriting. Then once you've generated enough ideas, you sort them into piles depending on how useful they are or how well they fit into the assignment.
Then you start constructing the outline, long after I would have expected to be told to do it.
The thing is, looking at a lot of my 'chaos drafts' I can sort of see that they're right back at that early step of generating ideas and information. The next step isn't for it to magically come together as a complete novel draft - it's sorting all the bits and pieces into what really fits the original 'assignment' and what doesn't. Even then, the outlining stage is constructed on the basis that you'll be adding and changing ideas the whole way through it, and the drafting stage is practically inviting me to write in whatever order I want. Overall, the book is the closest thing I've found to a reference for the writing style I've found myself adopting.
Overall, this book is easy to read and the process it describes is easy to follow, but also easy to adapt if you're someone like me who already has a few established quirks. It's going to be extremely helpful for the coming Camp NaNo month. I only wish I'd bought it a bit earlier so I had more time to get myself sorted out.
I bought it from Booktopia, but I assume it's available from all the usual retailers.
