Should I get myself a mid-life crisis motorcycle?
I get the same feeling sometimes, to counter it I download the practical test standards for commercial pilots, transpose a few of the maneuvers like chandelles or lazy 8s etc on to the kneeboarding and go out and pretend I'm on a check ride, ticking off each maneuver after doing a practice attempt then absolute best effort " check ride" example. On the way back I have started making every approach to my home field a practice engine failure.
