Then the next level would be to stop worrying about yourself so much and focus on your opponent a lot more. Find people's habits after you perform a move or try to see what they want to do if they are cornered or in the middle of the stage. Everyone has patterns which means you should already know how to punish every single move in the game with every move. You have to know exactly what Fair can punish and what it sucks against. Meaning that I personally practiced these things A LOT, like telling my friend to do Fox SH nair only then FH nair then DJ nair. All different timings then I tried to apply like WD back grab, CC jab, dash away pivot ftilt or jab, back jump Fair so eventually i know exactly how to do it, it was just a matter of doing it in the heat of the moment which was much harder obviously. But then that's where the habits come in. You can see it when they jump after doing it so many times, i dont really have to commit to anything, i just need to be spaced correctly so i do not get hit.
So for habits, well it was a combination of all that training + knowing exactly what they want. Like at "that" spacing, do they like to jump and Nair/Bair? Do they like to DD? Laser? Go on platforms? Shield? Theres not that many options, it's all about where they are. When they are cornered, its highly likely they will take defensive options.. in the middle they will likely try to bait you with a dashdance then attack you. Knowing that, I can bait them instead and make them whiff attacks.. then it would be my turn to gain the middle stage.
