Re: Money music and passion.
I suspect that amateurs are all passionate. Whether they are passionate about the music, drumming or being cool is another matter.
I suspect that pro's are mostly passionate. Those who aren't, were at least once passionate enough to reach a pro level.
I doubt too many drummers are cynical about playing. Some pro's I've spoken with in the past came across as a bit blase at times, but it smelt like affectation to me.
