My brother had an IQ of 148, he would have lived under a bridge before sitting behind a desk. Dropped out of HS the beginning of his junior year, went to work in construction and hot tar roofing, rode with the Hells Angels for awhile.
He never minded hard, back breaking work but couldn’t handle authority or structure. I think the one thing he really enjoyed was playing and writing computer games during the off season, back in the Commadore era.
Seems to be a problem with many high-I.Q. folks. Can't handle authority and structure. My younger daughter's husband has a high-I.Q., but can't and won't work for anyone else. Has problems interacting with other people on a social level. He runs his own business out of his home and is successful inventing electronic gadgets. Now his daughter (my grandchild) is exhibiting many of the same characteristics as a three-year-old. Extremely smart, talking full sentences before she was one, and loves taking things apart and rebuilding them. But has problems with other kids her age, wanting control of every situation. I.Q. is not everything (speaking as someone with a genius I.Q.).
I think it’s a shame that a lot of bright kids go for “desk jobs” simply because that’s what’s expected of them. Dropping out of high school sounds pretty extreme though, hope it never came back to haunt him.
