The use of spaced repetition memory systems has changed my life over the past couple of years. Here's a few things I've found helpful:

I've memorized about 9,000 cards, over 2 years.

The single biggest change is that memory is no longer a haphazard event, to be left to chance. Rather, I can guarantee I will remember something, with minimal effort: it makes memory a _choice_.

Rule of thumb: if memorizing something will likely save me five minutes in the future, into the spaced repetion system it goes. The expected lifetime review time is less than five minutes, i.e., it takes < 5 minutes to learn something... forever.

that rule of thumb originates with @gwern [https://www.gwern.net/Spaced-repetition#how-much-to-add …] by the way
