It all comes down to muscle memory, so it might be helpful to actually force yourself to do something different. For example, for like 3 rounds, don’t let yourself jump forward, ever. This will teach you how to approach from the ground and set up some game there.
And going for the same setup every time just means you don’t know enough setups, spend some time on the Character Subforums and look up some new setups, then go into training mode and learn what knockdowns/setups will lead you to a new setup.
Not much to say other than “don’t do it”. I found when I was learning I had to conciously plan out every single jump. Before jumping I would commit to a move in my head: “I am jumping to perform a crossup mk.” and once I jump, if I’m no longer in range to get off what I planned, I just empty jump. I used to get caught by tripguard all the time because I thought jumping without hitting a button would be crazy. It’s not!
But yeah uhh… you gotta just practice a lot and tell yourself not to go on auto-pilot. Play people that are better than you, like a lot better than you. Find the best person you know and try to beat them, chances are once you run through your tricks - they will be on the lookout. You either adapt, or get sent back into training mode.
