Good article. Its what I try to tell girls when they say they're bad at math, of course from a different aspect. They don't need a better teacher, they need someone to show them there's nothing about them that makes math harder. The same applies to sports and programming. Sure you can't be the best at everything, but nobody ever is. Even Einstein couldn't find the grand unification equation, and you don't need to be Einstein to be good at what you want to do.
