That actually doesn’t sound too involved to me at all. I’m probably much closer to your end of the spectrum when it comes to longer projects.
I’ve found that the more complicated a story gets, the more useful it is for me to seperate “what happens” from “how it happens”. I can make a structural decision that looks perfectly logical on paper, then get down to the actual scene and realise the character simply wouldn’t behave that way anymore.
At that point I’d rather change the plan than force the scene to obey it.
What I really like about detailed outlining is that changes become easier to judge, though. If I move or remove something, I can usually see what else it affects instead of discovering the consequences 80 pages later.
For short pieces I’m much looser too. But with anything long I think my brain just wants a map before it starts walking.
This is me to a T. Outlining and pre-writing is how I think it should go. Then I start the draft and by the time I reach a particular scene--say Chapter 10--I know that the plan in my outline and pre-written versions don't work anymore. Either they're totally wrong and need to be taken in a completely new direction (a complete revision) or they need some minor tweak on the page that is nevertheless significant in regards to some element of the story, even if that is simply to show that the MC drives an all electric vehicle rather than a gas car. That still shows his opinion and commitment to environmental issues.
I haven't looked back in the thread, but I think I've said my "pre-written" versions of scenes are like a first draft. If I may be pedantic, they're actually more of a rough draft, after which comes the more finalized first draft that is then edited in the context of the entire story to create a second draft--or simply complete a first editing pass before giving the story to crit partners.
Oh wow! How long do your outlines tend to be? I think I get the broad strokes in there, but my outlines typically top out around 3500 words. It sounds like yours are probably quite a bit longer. I see the merit behind it.
I'll talk about the pre-written versions of scenes rather than the outlines. Sometimes, they're only 200 words shorter than the draft version. Other times, they're 1k words shorter. It depends what I'm doing with that scene.
For instance, I feel confident in writing character and setting descriptions. So I often leave those out of the pre-written version, only including a note for myself to add X description at this specific point. Btw, that 1k word difference was something that actually happened with one of my Lake Proper scenes. It was only supposed to be ~700 words. The draft version was a bit over 1700 words. In that case, I think the MC's discussion with another character needed to be expanded, or it expanded naturally as I wrote the draft, resulting in the pre-written version becoming more of a guide than the rough draft that they often are.
This is so true. Even just the process of writing is so mind-consuming. It took a solid 8-9 days before I really came down off the mountain and rejoined the living world after writing Lyetuna.
Sounds like you had a really good week there!
That's how I am when I write a whole lot in a short space of time. Runners have their high, an dso do writers.
Yes! I totally get this...also yes, morning creativity are two words that are perfect strangers in my vocabulary. I probably should have added that when you asked about how the hell I got 213k words in 72 days, but consistency was the big one. I usually used late evening after my wife went to bed. Hard to beat that night owl creativity!
Actually, mornings are the best time for me to write. Just not the moment I wake up. I often spend weekend mornings writing in a coffee shop or cafe--I'm single, no kids, ah the bachelor life

Between my morning routine and caring for and playing with my cats, it takes me about 90 minutes to get out the door after waking up. That's the perfect amount of time to get my mind into gear and ready to be creative.
That said, I finished the first edit on Lake Proper! That was Thursday night. So I spent yesterday morning (Friday) looking into submitting a short story (which I previously did and got rejected for, so I didn't sub again) and then in revising one of the opening scenes in Lake Proper which my crit partners all universally detested. They had good reason and everyone complaining about the same thing led me to find a solution. The scene is much better now, if I do say so myself.
Lastly, I'm writing this from a cafe on Saturday morning. After spending the last two weeks on Lake Proper edits, they're finally done. So now it's time I turn my attention to another project. As discussed already, I have the far future, adult scifi Relics story that I set down due to a minor sticking point (then Lake Proper took off) and I have a new draft of the middle grade urban fantasy Santaland to plan out. I think I'll keep Santaland for weekday mornings, as revising is similar to editing and that's worked well for an hour before work. Relics will be so much fun and, yet, I don't know that I've actually solved the problem I was stuck on. Then there's other old ideas that, sensing my hesitation, have raised their hands for attention too...
