That sounds familiar enough that it could have been cobbled from stuff I've written over the past…what, ten, twenty years? Eesh.
This is a really solid example of the life-success-grr thing that – well, I can safely say that *I* experienced, and keep experiencing – literally, to today.
There's a little bit to be said about folks like that (or us, or whatever) buying into the partial and misunderstood public-image of 'gifted', and thusly continuing to be confused and disappointed with ourselves. (Somebody else is more certain about what we can do, while we ourselves are not. They *must* have some answers, then, right? …no.)
Something I found, which I think has been useful, is that while in some aspects, 'we' may have MORE of some kind of capacity, facility, or some such than many, that doesn't mean we have ALL of whatever that is. 'Smart' doesn't mean 'knows everything and can figure everything out right now'.
Even regarding the tangly, and nasty subject of IQ scores…as intended, all it states is that somebody who is 20 years old, who has an IQ of 150, has the mental development of a 30-year-old. Smart? Sure. Ahead of the game a little? Perhaps. But suddenly possessing built-in, completely-formed superpowers? Not as much.
I think we need to take it a little easier on ourselves, in general.
(This being said, I could totally benefit from taking my own advice. Intellectually knowing vs. internally/emotionally assimilating…)
