I'm not sure it's a given that natural talent is even part of the equation. A decent number of the behavioral economics who have written popular books (Grit, Peak, to name a few) seem to be converging on the idea that talent isn't really worth discussing as a prerequisite to greatness.

That especially follows if you consider the luck factor mentioned in this article; is it really talent to have a unique way of looking at a topic that moves the topic forward? Or is the uniqueness merely a factor of the set of experiences a person just happens to bring to bear on a problem?

I say this because far too many people get caught up on talent, trying to find what their talent is, when they'd be much more productive simply obsessing.
