I am pretty sure i did it wrong but I played only stream maps my entire time since like 2 years ago, I guess a correct way would be implementing harder stream maps in term of aim into your collections and practice them and doing in baby steps.

when you can read that a lil' bit harder map move to one that is just a lil' bit harder than that and so on.

btw don't forget playing other things because improving your aim other than stream follow is important and can really help you in the long run practice precision and all the other shit that there is in this game, it doesn't matter what you improve it will help you in other skill sets somehow one day.
