Everyone on Wanikani uses it to better their kanji skills, I assume anyway. But is kanji your only weakpoint?
Besides Kanji, I have a weak point in my actually speakings skills. The language when I talk comes out clumsy, or unintelligible. Some would say that I simply need to use it more, which I concede is a good idea, however its hard to find the time, and speaking a foreign language to yourself on public transit will get you a few unwanted stares.
How do you make the time to fix your weakpoints?
