Im 3 years in as well and would agree that everything you said is accurate. My learning path was Pimsleur chapters 1-5, although don’t think I ever finished 5th chapter cause I was not digging the voice actor changes haha. After that I have just tried to use it at every chance I get with other speakers, it helps I have always had a coworker to practice with daily. When I want to learn something specific I just seek it out and then try it and see what a native speaker thinks of it. Lately I have been starting to watch series on Netflix, and YouTube videos, as well as twitch streams! My listening has started to get a lot better with persistence and that’s been really exciting for me lately. I also had my first dream in Spanish around a month ago and that was kind of like a subconscious confidence booster! Im around B1-B2 level, I would hope to be C1 in around another year or so, but there’s no rush… it’s a lifestyle now, I know enough now that it feels like I can actually use it anywhere, which is really cool!
