Think about how you study in other things. In school, you listen to the teacher lecture and you (Should) self-study by reading a textbook and do problems at home. For a more casual activity, maybe in a video game, you can record your gameplay and look it over to find mistakes, or ask someone better to play with / watch you play. What do these both have in common? You learn things, either from lecture / videos / reading / analyzing, and try to apply it in a problem, or in game.
It's not any different in chess. You learn things from books / videos, and you try to get those situations in game to practice what you learned. This could be anything from remembering how to play a new opening to realizing you've seen this type of tactic, right before you play it.
If you find that free resources on youtube feel lackluster, you may want to consider paid options. Personally, I found books to be very helpful. You may want to check out the Soviet chess primer and/or Logical Chess (make sure they're in algebraic).
If not, I'd recommend you check out Daniel Naroditsky on Youtube. I think he can articulate his thinking very well, and it would do everyone well to mimic his thought process. I don't watch much chess, so I can't really suggest any others YTs, but I'm sure others in this thread can.
I need some advice from more advanced players, what should I do? I really wanna study chess but I find all the material incomprehensible. Not to mention that most of the YT videos are pure clickbait.
I'd say I'm 2400+ today because of three things: reading chess books, playing to practice what I've learned from those chess books, and analyzing my games afterward to see what I could've done better.
It's not an easy path, of course. Chess is a difficult game. Losing a lot is part of the process.
But quality chess books are so valuable when it comes to improvement. I don't think I've learned much of anything from YouTube. But if you take away all the things I learned from chess books, I'd probably still be around 1400 or so ...
Idk I've never even opened a chess book but if it works for the op it's probably better but there are things you learn to from playing or watching you just don't learn from books and vice versa
