Until three months I thought exactly like you: “once I can write Kanji, I will do Shodo, once I am fluent in Japanese I will finally learn Spanish etc.”
That’s a limiting way of thinking. Maybe you think like that because you think you are not a good learner because you don’t like textbooks.
But think about it:
Textbooks used to be the only feasible way of compressing information and distributing it to many people until a few years ago. Now we have the internet (that would look like magic to anyone a couple of years ago!) and almost everyone walks around 24/7 with a smartphone. The possibilities are limitless!
I am already old, and as a child I loved knight rider. I would have cut my right arm off to get that watch. And now, without any sacrifice EVERYONE owns something like that a trillion times better.
It’s a total madness to confine yourself to methods that are antique. Textbooks are exactly that, look at it. You have a book full of made up wonky stories about Guptasan and Smithsan messing around with a WAPURO compared to youtube, Duolingo, online dictionaries, wanikani, native facebook friends, following japanese instagram accounts, amazon kindle with integrated dictionaries (you can make an amazon japan account easily, do you know that? They also have Mangas for kindle, they are really cheap btw.) etc.
The sad truth is, you might never become fluent in Japanese. Of course it depends a lot on your definition of fluency. I know a Professor who is researching about Austrian literature and is he fluent in German? Well, you know, there are really several definitions about that out there. Jay Rubin, Harvard? He hates Kanji, another way to put this is, he is a semi- analphabet in his chosen language
. The point is, do you think you are able to express what you want at the current moment, and you can absolutely reach that point. And it will change over time, and so will you.
The better approach is, to do what you want, because you are good at it.
You want to learn Russian?
Just do it:
It works well and it is free. Just takes a couple of minutes everyday and it will also improve your capacity to learn Japanese. In a strange way, there is no limit for learning other than the ones you set up yourself. But I recommend to write down all the vocabulary and sample sentences, otherwise I think it might not be possible to memorize a lot and probably leads to a certain frustration at some point.
