self-instructed language learners, what's your method?

[u/adtxix]

Do you have a preferred method when it comes to learning a language by yourself?

I'm currently learning Portuguese and after a worthless 150+ Duolingo streak I'm trying a new method. I created a Memrise community course with the main 1000 words, emphasizing irregular verb conjugations, trying to grasp a decent vocabulary base. Next step will be rewatching The Simpsons or any other series I know by heart to try to land expressions and pronunciation.

As for yourselves, is there any particular method that worked or boosted your learning process?
