One of the reasons I left the Mensa crowd. It was all ego. I joined telling myself I wanted to be around other smart people. What I found was anything but. And I wasn't any better. It felt good to pass that test and to be among the "smartest."
But, having a high IQ doesn't make you smart. It's a start, and it's potential, but without anything else, that's really all it is. I'm absolutely brilliant on paper. I have the degrees to back it up and can learn pretty much anything that's put in front of me with ease....EXCEPT, I still get my left and right messed up. I have zero spatial ability and the worst sense of direction in the history of humankind. I also suck musically. So yeah, it's all kind of a construct.
