I'd recommend reading this: https://docs.google.com/document/d/10bRzVblKVOsQJjTc2PIi1Gbj_LrsJCkMkh0SutXCZdI/edit#, it's quite comprehensive, the article linked in there as "Zipf's law" is particularly interesting (to me), I want to get good enough at Japanese to be able to understand native speakers, in both "normal" and "nonstandard" speech, to understand anime and manga, but not necessarily than the most difficult dialects, like regional dialects, and understanding how much more difficult it is to do that than to simply be able to hold a conversation is very important
