I tend to only write stuff down I learned from reading the book, then later turn these notes into flash cards. I feel the stuff that is obvious to me shouldn’t be written down, even if my notes then lack a certain completeness or are incomprehensible for anyone but me. I rather have notes of bits and pieces and tie them to the already existing neurological connections I have about the subject instead of trying to reorder everything in a coherent hierarchical sense. I feel trying to make a perfect summary of a topic is something that is not really useful to a single person from a learning perspective. Yea you can not easily turn your notes into a blog post, but you train your brain and that is more rewarding in the long run, I think. Also, yeah, Zettelkasten.
