Truth is, this goal has no limit. There’s no limit to “learning more Japanese”. But when I see how much I’ve improved, I really see that I did learn a lot more. However, this year I helplessly started to lack time, and the topics only started to get more and more difficult, so I knew my learning wouldn’t be very productive, and I quit [quit the photography class later, too].

So yep, this language probably has no limit of how much you can improve. There are such subtle things that really take time and practice to grasp. But I guess I’ll survive if I’ll end up having a conversation in Japanese. :]
