Just work in a couple of prominent research labs, like I did. You'll be quickly disabused of the notion that you're in any way "extraordinary". At best you can say that you know more than other people in your particular niche. But then you have to concede that other people know more than you do in their niche. There are, however, real freaks out there who know more than you in any niche they decide they need to know something in. What takes you year takes them hours. What takes you hours takes no effort at all - it's immediately obvious. Some of them are humble about this, some aren't humble at all. It can be fascinating or demoralizing, depending on how attached you are to the false notion of your "extraordinarity". Unfortunately for humanity there are only very few of such people. I can't help but think that this is how human mind is supposed to be, and the rest of us are just deficient.
