I’m learning German intensively at the moment and something that helped massively was watching a TV show I was v. familiar with in German (I chose BoJack Horseman). The main thing that helped was to have absolutely no subtitles (English or German) because it forced me to really focus on the melody of the language and pick it apart. I’d also really recommend finding a podcast series that you find engaging, because the conversation is just so much more realistic. My teacher explained that the most important thing is to surround yourself with the language in every way (music, YouTube, even changing your phone language) even if you don’t understand everything, because that way your brain will naturally start to internalise the language :-)
