Yes, but Mugsy couldn't be a swimmer! :D

I think the "professionalism" needed for giving a shit depends on what is at stake personally. You don't care much about the hairdresser or you expect them to be a bit quirky - but the dentist sticking stuff in your mouth! :D

My dad was an artist and without teaching me or having learned, I can draw decently. He sucked at math too. It isn't that it necessarily stops me from being a mathematician, but it could put in a much higher hurdle, making it functionally impossible, given all of the other factors involved in life, and distractions.
