what do you think when you practice to maximize it? your fingers?

Maybe it seems like a weird question but I see a lot of coments of people saying you shouldn’t practice mindlessly. And I get it. I shouldn’t practice the wrong fingering or the wrong notes or with bad posture etc but, apart from that, is there anything I should be “feeling” or “thinking”? should I focus my mind on something to tell my brain “this is important, please keep it in the muscle memory as fast as possible”? like, should I be hyper aware of my fingers?
