Yes, DS. I stopped at 170h because I want to concentrate on Japanese until mid-March. And yes, Japanese CI is brutally difficult for me. Grammar, the many particles, the countless possibilities to count something, it feels like every word has at least 3 different meanings. Crazy 
Last year I was looking for a new hobby that could be useful to me and that I could integrate well into my current everyday life. As I want to travel more, especially internationally, I came up with the idea of learning Spanish. When I found Spanish CI, I really enjoyed learning with this method.
So why am I learning Japanese? Because I’m going through my “I’m learning new languages” phase and because I think it could be useful in the future .And since I’m traveling to Japan for the first time in March, I came up with the idea of this little experiment. Japan also has the potential to become a country that I would visit more regularly.
Somehow it’s also funny to think that a German village boy speaks Japanese.
