My first thought was golf.  But, I would be making a lot of "dimes" off my friends, so that disqualifies that.

So....I'll go with fine wood working.  I'm trying, and I have made some nice things.  But, there are some people who just have a talent with it that takes it to another level.  

I'm assuming the parameters would include your can give away your talent for free/friends and family can enjoy it so I'd go with being a world class saxophone player.  Pianist is a good call too @ladyhawke.

I'd say being a world-class drummer, but I am actually a very good drummer who isn't making a dime from it, so I guess I'm already kinda there.
