In business there is a concept of working in your business vs working on your business. I approach chess the same way, by working on chess instead of in chess(worrying about details), I'm now 2000 elo on chess.com and I plan to go to 3000 elo aswell. My advice: Your mindset and approach to the game itself will give you a far better Roi than putting all this energy on minutiae.

@Ebombayed Chesscareer 1 opening, master endgame, set small daily goals instead of a big goal, stop when you reach your daily goal.

@Ebombayed Chesscareer Why not rated? And if you have time to analyze, why not play more matches?

@Agastya Yadav That doesn't explain a 300 elo jump in 1.5 months

@Alex Millul Ofc, it'd be amazing if I could also jump 300 elo in 1.5 months, that's why I asked what he did specifically.
