Glad you identified the over-blowing culprit. I have always done the same and it’s a constant struggle not to when I go out and gig. I have shimmers of brilliance when I forget all the lesson stuff and just relax/blow while on a gig.
I then have to re-ground myself when I get back to wood-shedding in my basement each week outside of gigs. I hope the amount/percentage of playing I do(range, endurance etc) on gigs while NOT over-blowing increases little by little over time. This cycle will hopefully give way to eventually reaching 100% based on my new way of playing. It’s a journey of steps forward and steps backwards I guess.
