As someone who worked for 20 years as a professional musician (and made a decent living at it), I can confess that most of it was spent playing other people's music and some that I didn't even like. I came to a conclusion; that creatively it was better to have a music career that was actually a hobby so that it wasn't corrupted by having my music linked to earning a living. Since getting a 'normal' job and using my free time to play exactly what I want to play has been musically liberating. I know of many music teachers who hardly ever play music because they are so fed up at the end of the day.
