Haha, if only your first trip through manga went that quickly… I’m in a book club for book 1 of Yotsuba right now. I’m currently around 50 pages behind, if not more. I think my first 6 pages in that book took me around an hour to actually feel like I mostly understood the meaning. Not trying to scare you, but seriously. @Neon_Kitsune is right. For such a simple, childish book, it’s crazy how hard it is and how dumb you’ll feel while you’re still learning. I tell my friends that there are Manga that I will read in English in about 30 minutes that would likely take me a week to get through, if not more, in Japanese.
Now… Back to your original question.
Apologies in advance for the wall of text, I get verbose easily in text, and I’m very passionate about avoiding burnout in studying Japanese.
I’m currently balancing full time work and Japanese study. I’m currently primarily using WaniKani and Bunpro together, and within the last couple months I’ve started to add in some listening through some Youtube channels. I’ve already hit burnout once since restarting my learning journey this January. I have the luxury of working in a job where I can take some time throughout the workday and knock out some reviews here and there without getting myself into trouble. That being said, my daily total for reviews pretty much completely caps out at around 4-500 between the two sites. My overall patience is a finite resource, and I find that I have to manage that resource diligently to avoid getting frustrated. I have some tolerance for being wrong (I’m learning after all, if I’m right 100% of the time, then I’m not learning anything new) but it can get frustrating to get things wrong. Pay attention to that when you do your reviews. I find personally, that I have a very easy time keeping up and doing large batches on WaniKani, but my tolerance on Bunpro is significantly lower. I have all of my reviews here on Cloze style, which really forces you to recall the information, but can make things a bit harder (mostly in a good way). As such, I typically try to limit my review batches on here to 20 at a time, and do many small batches, instead of large batches.
If I keep my current pace, I don’t have room in my life for any more learning resources than that as a daily routine. I have Genki I sitting next to me, and it only really gets opened on weekends where I have very few plans and a lot of energy, which is a rare combination for me. So my personal advice: limit yourself to a small combination of resources that you feel like you benefit from, and that you can do daily. Keep the routine. Doing small things consistently is going to benefit you far more than doing big things inconsistently, or dropping altogether. It’s nuts how hard it is some nights to force myself to listen to just 10 minutes after a busy day.
And one final bit of advice: With SRS systems, the choices you make today and this week will haunt you for a lot longer than you might think. Take on too much too fast, and you won’t realize how much you piled on until you keep that up for a while and get yourself good and buried. My first burnout happened after 3 months of maintaining just WK and Bunpro daily, and at the time, I think I was only doing around 15 or so lessons on WK and around 15 on Bunpro each day. I’ve done a lot since then to work on consistency in my reviews, and working smaller batches throughout the day. These days I do 25 lessons a day on WaniKani, and that results in around 150-250 reviews a day when you stay consistent with everything. So GO SLOW. Going a little too slow but maintaining a routine is far better than burning out and dropping everything for a year. After my burnout, I’m happy to say that I’m maintaining a streak of over 120 days, but I have paid a lot more attention to what I take on as a result of that burnout.
