So the article is associating exceptional musical accomplishment, with career success? Eh, I don't know about that. I know a lot of consummate professionals in various fields, who aren't playing at journeyman levels, much less professional levels. I think only in the movies do athletes, physicians, lawyers and elected leaders sit down at a piano and rattle off a difficult piece with ease, or rip off a great guitar riff. Bill Clinton was weak on sax - but it made a huge impression, because we've never seen a president even play. Without knowing who he was, he'd be in the lower third of any high school jazz or pep band. I'd love to see more professionals also play seriously, but its just not happening.
