For instance, I was flying back and forth, just playing between figure eight practice runs. I would take her down the feild, pull up into a nice 45 degree or so climb, then roll her over upside down and using up elevator reverse direction thereby righting the aircraft, in sort of a half loop. I've practiced this maneuver countless times on my simulator. I was doing great. Then one pass I didnt use enough power in the climb and she stalled half way thru the roll, by the time I recovered it it was going back the other direction (good) but INVERTED (BAD) since I didnt realize I was still inverted till I eased up elevator to climb. Fortunately I am a firm believer in the three mistakes high rule and had sufficient altitude to correct this oversight and keep my precious Arrow in the sky. (Amazing how fast she dives when I dont want her too LOL!)
That's not a stupid thing...that's a mistake made trying to push your limits and get better...and a mistake you A) recognied the cause of and B) recovered from successfully.
Hopefully it'll take you an entire LIFETIME to stop doing THAT!
