Really, I have little piles everywhere around the house I tend to park for any length of time; I've never been able to do flashcards since my mom made me do them a ton when I was little, one of the ways I just do not learn.

I grew up the opposite; I never directed my learning in any particular direction, just picked up everything by curiosity and osmosis. I've only discovered in my 40s that you can use tools like Anki to just relentlessly hammer a subject into submission i.e. you can choose to know stuff instead of always having to be spontaneously fascinated by stuff.
