I think this article roots to the kids narcissism - just because you have an high IQ, does not mean you will become somewhat more important, more powerful or more successful than "Joe the plumber". Let me ask you this: Was Godel happy? Was Alan Turing happy? Even though they both were brilliant and had academic success, still - their personal lives was pretty much a sad state of affairs, and depression characterized their lives. Brilliance and success is not happiness. You are 20 (!) - I was around 25 before I found my academic passion, which by that gave me a inner calm. I wish you the best of luck. But to expect every piece to fall at place at the age of 20 is plain naive, actually a bit provoking. In addition to the large tasks here in life (like education and career) the small enjoyments like coffee in the morning, listening to the birds, getting a proper workout - is what keeps you smiling, or at least, it's what makes my day swell.
