Oh, flash cards. I’ve never used them but memory is a muscle and it must be exercised. There has to be something more fun, though.

Spaced repetition, through flash cards or another tool, is pretty much the gold standard in terms of optimizing your memory. It really doesn't get much better than that. Flash cards aren't super exciting, but realistically even 15-20 minutes a day is enough to learn and remember a ton of stuff.

I find that the subject under study dominates my sense of fun, no matter the format of that studying.

The trick is to effectively study subjects you’re burnt out on or no longer have that magnetic attraction to.

Do you have any tips? I haven't really approached this category because it feels like a lost cause.
