I do Japanese for a number of reasons.
It occupies my present, and it will remain a part of my future (in terms of family and vocation). Love it or loathe it, I’m stuck with it!
It’s a sizeable challenge—a good thing. If I manage Japanese, I’ll manage any language!
Also, it’s fun. One might say that I’m addicted to it.
I plan to spend a third of my time on Japanese, another third to build up previous languages, and the final third for starting others. My next language-of-the-month is coming up. I do believe that I’ll start Spanish.
