Late response to this old thread, but I just thought I would add what keeps me motivated!
I find that the thing that really gets me going is when I stumble across some Japanese, be it on my blog or when I’m reading or watching something, and I get it. Like, the other day I stumbled across a image set from an old, cheesy Japanese horror movie, and I could understand 90% of the text!
It just feels so good when you start to lose that dependence on translations or a dictionary.
Pretty much every time I have this moment - and it’s happening more and more - I run to WK and finish out my vocabulary lessons. My vocabulary lessons always pile up, because I just don’t really feel like doing them, whereas I always finish radicals and kanji so I can go up in levels. But then I see vocabulary that WK taught me and I think, “Well, what if some new Japanese media comes my way, and I’m just a few lessons away from being able to understand it!”
And that’s really how I keep myself going, is just by letting a wave of media come my way and sometimes things stick and I get really excited.
I’m sure that’s a big motivator for everyone, but just thought I would share.
