There’s just too many things I’d want to learn, but I probably can’t do everything at once. And I also don’t know where to start when it comes to basically any topic.
Courses could absolutely work, but they tend to be paid, so that’s a problem.
How do you approach learning new material, especially if you only know a goal rather than a full/partial path?
For the languages, first of all I’d definitely second schipelblorp’s post about Anki.
But also, shameless plug, you should join [email protected] (if you haven’t already). Participate in the weekly threads to give yourself some accountability, ask for tips from other learners, etc. I know there are also some specific communities for learning German.
