Quite common in website design and product development, but also for testing hypotheses on yourself.
E.g. you want to see if coffee affects your productivity, then you do 2 days with coffee, 2 days without, 2 days with, 2 days without and so on. And write down how productive you felt each day. See if you can spot a pattern.
Common knowledge: the best flashcards are those you make yourself.
Some years back, I thought I could compromise, on content I had already read and understood. I tried to integrate some pre-made #lesswrong decks from www.stafforini.com/blog/anki-decks-by-lesswrong-users/. But they were not fun to review. The cards were not how I'd have written them, had the wrong emphasis, flagrantly violated Wozniak's 20 rules, etc…
So now I maintain a deck that's purely my own creation. Better.
Is sharing decks pointless then?
I think not. When summarizing an article/book in flashcards, I sometimes wonder what other people have made out of the same article/book. I'd like to see them. Not to copy verbatim, just get ideas for what questions I can pose to myself.

This is one of my methods to begin thinking.
After spending months without any real self-awareness, this is an easy way to start being aware again.
Load a backpack with a tent and some drinks of choice. Find a potential camping spot where you can drop off the backpack, then walk more. No time limit, no destination. Ideally with drinks in hand, I like it as a partial distraction, but YMMV.
The tent need not be used. I just find it frees my mind to have, so I can stay in the woods for however long I feel like and nobody's expecting me back.
