I can give you some books that I found helpful, but you have to remember that this is just what I used as a starting point. Ultimately the best stuff is things you’ll come up with yourself. And no doubt others here have plenty of their own suggestions. Look out for someone who is a grand mastery of memory too, chances are their recommendations are worth considering.
I would suggest “Speed Memory”, by Tony Buzan. I think it came out in 1971, but don’t let that dissuade you, the techniques you’ll gain from it go back a lot longer! I use Anki as my daily SRS machine. Very useful, especially as it has a decent community behind it so if there is a feature you’d like there is a chance someone has already written it and you can simply download it. Not that that’s necessary right now. Out of the box would be just fine to start.
Let’s us know how you go with it along the road. What works for you, what doesn’t. You’ll likely encounter similar issues that many of us have had over the years.
