This is the dark side of believing in innate talent. It can beget a tendency to assume that some people have a talent for something and others don't and that you can tell the difference early on. If you believe that, you encourage and support the 'talented' ones and discourage the rest, creating the self-fulfilling prophecy. ... The best way to avoid this is to recognize the potential in all of us — and work to find ways to develop it.

People can be talented in a variety of directions. I've known people who can effortlessly solve math problems while carrying on a conversation, while I like to joke that I've never been sure how many fingers and toes I have. We just aren't all alike, and that's OK. The author you quote approaches the question by devaluing genius. Better to just be the best you can be and stop fretting about how you compare to others.
