A couple weeks ago I started studying Japanese and now I came to the realization that I probably will never reach a very high level in any of the languages that I study because I'll always start to learn a new language.
My goal in learning a language was always to be able to read books/comics and to watch movies/series and Youtube videos, never really to write or to speak it. So, as soon as I reach a level that I can consume content made to native speakers I can't resist jumping to a new language. I maintain the others languages through input, but I kind of stop the deliberate study.
I fought my will to start a new language for a long time but I couldn't anymore, my interest and curiosity to study Japanese was just too great . I learned the Hiragana and Katakana syllabary (components of the Japanese writing system) and now I'm having a blast learning the Kanji, the Chinese characters. I thought that this would be a very dull part of studying Japanese but at least for now I'm really enjoying it. I'm also diving deep into the Japanese culture, that I realized that I knew very little about. I know that this "honey moon" phase will eventually slowly wind down, but until then I'll keep haven fun.
I just don't have the discipline to focus 100% in a single language, so I'm embracing the process and not thinking about reaching a goal. Maybe I'll change my mind in the future, but at the moment I accepted the situation and I'm happy with it.
