Very good. I did a huge language deep diver a decade ago. The best I ever came across was the “Pimsluer” method. Guy was a genius.

I picked up conversational Spanish in 30 days.

I didn’t continue unfortunately - life gets busy - but I’m sure if I did a whole 90 days, and then stayed in a Spanish speaking place, I would’ve been flying by now. The good thing is; I can understand pretty well, and a lot of that is residue from the Pimsluer stuff I did.

Definitely worth checking out.

I really like Steve's website, LingQ. It's my favorite interface for reading in other languages.

I didn’t watch the video, anyways, from my opinion the best way is to speak the language you are trying to learn (to learn using muscle memory not only your brain) and listen to it from different people.
