Its a style of writing that's not everyone's cup of tea. The short chapters are meant to keep the narrative flowing and be a book that you can keep picking up. I believe Rothfuss said he starts his novels with a detailed outline, so it seems his writing process is expanding his outline into scenes, combining those scenes into chapters, and then connecting them to the overall narrative.

Personally I love the way its structured.

2 novels and a novella

I avoid fan groups for any given book, series, or author except when I want to discuss a book or other work. The internet is full of stans who have picked some series, books, or even bibliographies of various authors to be the hill they defend to their dying breath. Let them do what makes them happy and go do what makes you happy.

Read what you want, when you want. Don't set a goal like x number of books a year/week/month. Recognize that other forms of media have value too. Take a break after books to think on them. Put the book down and spend sometime outside or going to a museum or whatever you like too.

You won't be able to afford living near the metro. You'd better figure out how you are going to get to it.

It may be doable, but idk if that is do if you need to be close to the metro. Rent near the metro is much more and most the places you could afford are driving distance from the metro.

To be fair, some were out of his control due to covid19 pandemic.

There are pocket versions of lotr too.
