I’m currently in the middle of learning a new language as an adult. I’m using Duolingo for the formal grammar lessons, but most of my learning is honestly coming from music, audiobooks, and reading comics. Recently made a few friends who speak it so that helps too.
It’s what you make of it. Some people don’t make anything with theirs.
Personally, for me it’s to form community and to leave a positive lasting influence on others. Except fascists, they can rot in hell. For others, it might be to learn as much as they can or to impart their wisdom onto their children.
