Cam, you might also like to check out Talent is Overrated by Geoff Colvin. He elaborates further on the 6 rules of deliberate practice.
The topic of natural talent is one of my favourites, because I don't believe in it and I think others use the idea of gifts bestowed on someone from birth, as an opportunity to let themselves off the hook - for their own perceived lack of ability and lack of willingness to acknowledge exactly how much work goes into becoming really good at something.
So when you discuss it with people the conversation can get quite heated.
I like what Ryan said and I say this to people myself that to confer natural talent on someone is actually an insult to the hours and hours of (deliberate) practice they have put into their skills.
Thanks for writing this article, it's great to have someone as accomplished as Ryan debunk natural talent too.
