How do I get better?
I have an idea.First,do lessons and also solving your daily puzzle.Second,compete with bots or do chess analysis.Thats it! Get better with chess;)
My advice (as a chess coach and 2100+ player):
Learn and apply the most important principles of chess.
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.
Learn how to be more psychologically resilient.
Work on your time management skills.
Get a coach if you can.

I just cant get better in the game.
