You should absolutely pay attention to how you sit if you’ve learned to it wrong. Once the proper habit is built you no longer have to pay attention, just check yourself once in a while so you don’t slowly go back to the old habits. I unlearned and relearned sitting habits in my 30s after having back pain. Now in my 40s im doing much better than in my my 20s. Once in a while I catch myself in a bad sitting posture but it seems to be getting better and better.
