I agree with your tips, but what I would add is that it is very difficult for you to be VERY GOOD at several games, the best thing to do is to dedicate yourself to just 1 game, and when you are VERY GOOD at that game, we will certainly The next FPS you play will have a much better sense of aim and recoil than most players.
So always focus on playing just 1 game, and become good at it.
