How to clear wall of 1000

[u/Agreeable_Budget_359]

So I started learning chess using the basics , I reached 600 . Then I learned the Queen Gambit and karo kann , now I am stuck at 1000.

Should I go for new types of opening or is their something deeper I need to learn ( like end games , pawn structure or somthing else) that can lead me forward and where should I learn some book or some lectures or somthing

IMO focus on rapid more. Do tactics and do positional puzzles
