You’re clearly humble, so keep that up.
Don’t overthink your problem. You said you were off altitude. Problems feel massive in UPT, but try not to overthink it. Small problem, small fix.
I oversped the flaps once and automatically hooked. Spent the next day in the fake sim (CPT?) talking myself through touch and goes. Made myself a head case and hooked a few rides in a row.
Also, take time every week to get as far away from UPT as you can and just relax, whatever that looks like for you. Run, ride, turn wrenches, whatever. Get plenty of rest every night.
Despite how you probably feel, most people struggle at some point in UPT, with something. Keep your head down, your chin up, and be a good dude with a great attitude and you’ll be fine.
