Some background: I took Japanese I in college in 2021, in the last semester of my senior year, which covered Genki I chapters 1-5. Aka basically up to right before te-form.
After that, I worked in retail for a year and didn’t get very much practice, but since August of this year, I’ve been living in Japan working as an assistant language teacher on the JET Program. Most of the stuff I do at work is 95% in English, and the only studying I’m able to do at work is Wanikani. I haven’t been able to meaningfully start going through Genki again from where I left off because I find it impossible to concentrate without listening to music while I take notes and/or watching a video explaining the chapter’s content. However, I’m not sure how people at work would feel about me listening to music while taking notes from the textbook or watching stuff on youtube so I don’t do either. I try to “read the room” and pretty much never see the other teachers using headphones unless they’re listening to audio related to their lesson so I don’t want to step on any toes by looking like I’m goofing off on youtube at work.
As a result of this, my grammar is stalled at Genki chapter 5, while my vocal and kanji are now far beyond thanks to Wanikani. Given how things are going, I wonder if anyone actually has done the “wait until level 20 to start grammar” strat even though in my case it would not be starting grammar from zero.
Also, any general advice on my situation because I’m always hella tired and do not have the energy to do textbook study after work as much as i try to will myself to.
