Is There Any Value in Studying the Language?

I don't think that can come from getting your mistakes corrected. Most native speakers are very bad at articulating the language. The only way you're going to get that is by exposing yourself to the language for like thousands of hours and letting your brain kind of pattern match all the different situations. It's actually better to wait to speak until you already have that intuition so that you can kind of like guide yourself, build good habits first time.
