Reading the question I was in disbelief: what a miserable way to experience literature (even non-fiction). Just read the book! Enjoy it! What possible goal could be fulfilled by this kind of incessant note-taking?
Really brilliant people, the kind of people that can take different ideas from different sources and synthesize them into new things, they don’t read books in this way. They just read them. If they do take notes, it’s to check something with some other source or if it’s something they want to remember. They don’t make “120 notes about the most interesting ideas” or whatever. That just sounds like some kind of obsessive dedication to a note-taking system, not a way to actually learn anything, let alone as a good way to experience culture.
