improving game

I watch a lot of chess videos…I don’t think they’re helping me. I’m stuck at around 900…am I watching the wrong stuff? How can I improve my rating? Online chess classes? Maybe some people have got it…some don’t. Is chess talent natural or can it be taught? TIA

PS…if I’m getting tired of playing e4 Italian/sicilian openings, should I just pick one I like and get good at it?

To see what you’re lacking at in chess analyze your games(you don’t need review) and see where you lost advantage and don’t care how much except if the move is impossible to find or if it’s just that you lost 0.3 advantage. For example this game

This game shows that you blundered so you have to fix that and is that a result of bad videos or not enough content? If no then find a way to improve on that from videos that have that content and if yes then there are always better videos online from good sources. You’ll find what I’ve learned throughout my journey here from online and experience.
