As someone who learned German, forgot it and re-learned it, it's also a terrible method to learn a foreign language, unless you're really motivated by speaking with other newbies.

The best approach with the most evidence for sucess is Comprehensible Input[-1], which requires nothing more than access to content you want to consume in the language of your choice

Ironically this was the most helpful youtube and twitch ever were for me, since I find mainstream German TV to be pretty bad (I find the same, or worse, with American TV to be fair)
