New aspirant

Hi I am new to chess, joined 20 days ago. Initially I was just playing casually, but gradually staring paying attention to my moves, and honestly started loving the game. I am currently rated 750 on chess.com and want to improve my game and expand my knowledge on tactics and openings. Playing regularly.
Experienced players pls guide me.
My id: OR-222 (last game I played was a mess 😊, but still won)
