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

I think I got it from http://SuperMemo.com .

It's pretty likely I got it from SuperMemo. Ironically, I don't remember. But then, I didn't put the source in Anki...

Incidentally, a few months ago I checked the rule of thumb, based on my average card review time, frequency of correctness statistics, and Anki's spacing algorithm. It came out to around 2-3 mins for an average card, based on reasonable multi-year extrapolations.

How consistent are you? Say over the past 3 months, how many days did you miss? Any advice on that? Because sometimes I miss out a day or two, and when I get back to it, many cards feel a little "out of touch"
