Well…
When I’ve been on WK over the past few months I’ve just been doing ‘review maintenance’ - not really learning much at all and even then struggling to get to the bottom of my reviews. But I pushed through a few days of veryl ow motivation, doing 80-100 at a time, until I finally got into a groove and was able to clear out my pile. I just learned my first new set of kanji since the spring!
I get it though - it’s difficult and if you want to keep learning then it can really be a misery. The worst when clearing out a review backlog is messing up many many items in a row and falling into a spiral of self-doubt. But it’s just the uglier side of the SRS doing its thing. If you can keep going through the downturn you can eventually have them stick in your brain again.
On the plus side, during my break I have done some reading and also a bit of anime with JP subs as well as conversing with a couple of friends!
Good luck with whatever approach you decide is healthiest!
Months wanting to do Wanikani but lacking a desire for anything. It was like a second wave of pandemic fatigue for me. I’m back and on it! Working on remembering a lot of things and going back through and resurrecting some things. Look at the reviews!
