When I took early retirement I had a number of option for my musical ambitions. Taking exams and going to the conservatory was a viable option (and suggested by the accordion teacher at the conservatory), but then I considered what I would gain from the experience besides a "paper", considering that I already played the accordion for 40 years, with a lot of classical and baroque music, and was conductor of an accordion orchestra/ensemble for 30 years, and have taught accordion to beginners enough to know that I certainly did not want to start doing that again... Another option was to devote more time on making arrangements for ensembles. And yet another option was to learn (properly) how to maintain and repair accordions, so that my playing could benefit from having well-maintained accordions, and maintaining the accordions of friends I play together with. In the end I decided on the latter two directions: making arrangements and learning accordion repair. This certainly have given me a lot of satisfaction in what I do, something that I'm sure exceeds the satisfaction that exams (with always very subjective ratings) could have given me.
