You should work towards improving your chess game content.
Rating is just a temporary number.
In bullet chess one can have a rather high rating without even play chess well, or producing something sensible.
To improve your chess skills and game content, you best study and train and play and analyze.
Here's some suggestions :
1) Analyze your own games (Botvinnik was maybe the first well-known GM who claimed this is important).
2) Go through, and study, annotated chess games, annotated by chess masters or strong players.
3) Study chess books and chess videos about chess strategy and endgame knowledge, and the chess classics games (Morphy,Alekhine,Spielmann,Fischer,Tal,Smyslow etc.).
4) Join a local chess club where you can play otb chess against equal or stronger players and analyze the games with them.
It is important to avoid playing only against weaker opponents, because it is unlikely you will learn a lot from them.
5) Play rated games, so that you can every now and then look at your "rating progress" just as a rough indication.
Your current classical rating still has the ? sign.
Good luck!
