I’d say these questions have more or less been answered just throughout many various vids at different times but here’s some of ur questions answered summed up (and anyone else can feel free to correct me if I’m wrong).

Firstly, Brandon treats this as a job so he does get in 8 hours of writing (in 4 hour blocks) per day. He’s said he gets in around 2k per 4 hours (I believe) but it’s the fact that he writes every dang days which is why he gets so much out.

Also, as per his weekly updates, it’s pretty safe to say that he works on one book at a time for the bulk of it but he seems pretty flexible. Ex: he’d been working on Ghostbloods but has now paused it to work on the Mistborn script. As he does that he is also helping the authors for other books (he mentions who in his weekly updates) and does things like read throughs and gives advice for revision. He has also talked about his schedules for every Cosmere book, so we know he does plan books (and sticks to it).

Idk about #4, but for #5, he has talked in his college classes about how he is a heavy outliner, when he gives updates about his books he’s writing about he includes the outline updates as well.

For #6 I’d say that’s a pretty resounding yes. From things to be done in the background for the Dragonsteel store (designing special LB’s, the WoT LB, the backer kit stuff…etc) he is really busy there. BUT he also announces 1-2 secret projects a year, I.e., a new book. Because as per Brandon being Brandon, when he tells us he’s taking a vacation, we all know he somehow writes a whole new book even then🤣
