"Sometimes I lose on time" ++ Play with increment, preferable 15|10.
"or tilt" ++ Whenever you lose a game, stop playing and analyse it first.
"advice on what I need to improve on to reach 2000" ++ Analyse your lost games.
Study annotated grandmaster games. Study endgames, especially rook endings.

@tygxc Thank you , I appreciate your feedback , GM games I've never analyzed , I like that idea. But I don't think I'll play with increment. I feel like I should adjust to 10 min rapid , since I want to play blitz aswell when I reach 2000 rapid. I dont want to be too slow with my calculations. But I will keep your word in mind , thanks again.
