First step is to consistently play chess a minimum of 4 hours per day. Dont play fast games you will not improve if you play fast games. DO not only play games you also need to do puzzles and opening prep try to go to as many fide tournaments as possible. This is my fide profile https://ratings.fide.com/profile/33399131/calculations as you can see i have some good numbers. You also have to find your playing style do you like to play attacking or positional or defense once you find it you can prepare according to your style or you can play opening which could lead to both positional and attacking like the roy lopez, this is completely based on your style of play. You can also have 2 lichess acounts 1 for tournaments and 1 for normal play. Do not pressure yourself cause if you do you will not play your best chess, I played with freedom and won against an Im in 25 moves here below
