How do other people study? I'm constantly vacillating between the ideas of taking notes and making flashcards, or just making flashcards. I'd like to study everything the same way, but it seems like for less technical subjects like philosophy making flashcards wouldn't suffice and I'd need to take notes. For some reason the idea of taking notes for some subjects but not others is uncomfortable to me. And I'm also stuck between taking notes on the literature I read or just keeping a list. It's getting to the point where I don't even study or read anymore because I feel like I need to figure out the best way first.

Ideally I want to take no notes whatsoever and just make flashcards in Anki, since it's quicker and I never look back at notes anyway, but I'm paranoid that I'll be doing things sub-optimally. Does anyone have any suggestions for what to do? I mostly study math and science.
