There's still this idea that people who learn Japanese because of anime aren't serious and won't do well.
It's a myth. All you need is passion enough to get you through the hard parts of language learning.
Looked up Japanese courses in UK universities - there were 6. Went back to school at 20 to get the A levels I needed. Made it to uni at 21.
My motivation: to understand anime without subs
I didn't drop out, but I was right. By the beginning of 2nd year, my Japanese was good enough to make my first Japanese friends.
My motivation to understand without subtitles didn't change, even though I considered dropping out many, many times.
And despite that listening goal, my speaking got really good.
After that, it was good enough to work for Japanese bosses, live with Japanese housemates.
All from that one wish: to understand anime without subtitles.
But thanks to all that anime and TV watching, I grasped a lot of the slang, rhythms, and intonation that made it easier to connect with Japanese people
This thread came from those classes:
Combined, those things qualified me to have film reviews published in books on Japanese cinema, which led to me freelance writing full time for film and TV magazines.
Anime is also the reason I met my now-fiancé. The relationship is recent, but we met when I was my university's anime society secretary 15 years ago.
And I know that's true of many, many others inspired by anime to learn Japanese/drawing/animation/writing/singing/etc.
