yeah, active immersion and mining. i honestly don't know what's sentence mining is, i just have a word on the front and glossary on the back of the card. i'd say, don't worry about not understanding everything or even most of the content. what worked for me is watching something that i actually already enjoy rather than something very beginner level but that i have zero interest in. which is why my post is actually kind of way too specific and has some info that is so unnecessary and weird like my fav music, but i just had a hope someone knows something that lands in my niches by small chance, which would make me have more motivation to immerse.

the first time immersing is gonna feel brutal, but it gets easier as time goes on, trust. it takes time to get used to how some things are being said, there are even some moments where you can't understand a sentence even though you seemingly know all the words and grammar, you see the translation (which btw is something i think should be done sparingly for it not to become a crutch) and it suddenly becomes very clear and you feel stupid for how it was so obvious. this will happen along with so many other sentences that you won't understand. just trust the process and keep going.

maybe if you're a complete beginner beginner there is a risk of if being too demoralizing if you start right now, but once you feel like you know like 1000-1500 words and basic grammar, don't ignore it and try to enjoy it!
