This isn’t really SRS-ing (which for the newbies means Spaced Repetition System). This is something I do when again, I’m idle, which happens quite a lot. I’ll have a word list of Heisig Kanji with me, and practice writing them. I will highlight the stories that come to me easily and work on making better stories for the others. The list in the picture has 83 words, so it was great practice!
Naturally, the list can be modified and you can walk with it anywhere, write in the lobby of your job interview, or while sitting on the train. This has nothing to do with SRS, but its just a cool way to pratice a lot of words without having to squint at your phone, or if you aren’t near a bigger PC to Aniki.
