I don't think so. Passion, in this context, generally means an intense motivation and desire to engage in some activity because it gives you some kind of enjoyment. Since people usually get much more enjoyment from an activity they've mastered than one that they are very clumsy with, they're likely to become more passionate about it as they become better at it. That isn't a guarantee, though. It's entirely possible to be very good at something but not really enjoy doing it.

Maybe that's what passion really is - the satisfaction one gets from 10,000 hours of sweat and tears.

Perhaps a suitable-enough replacement? :)

I think Stephen Stills (of Crosby Stills and Nash) would agree.
