IQ does matter, but so does hard work and common sense.
Glad you br ought that up, innovative. My son is a genius, but consistently fails at work because he feels so superior, he just can't fit in...and other reasons, of course.
OTOH, I am just short of gifted, but I have high social skills and KNOW HOW TO DRESS. I always got wonderful jobs that I wasn't really qualified for. Learned on the job, got better as I went along. My genius son is still trying to find himself in the real world.
My daughter, OTOH, is not even close to genius level, but is persistent, a very hard worker, and makes more money than anyone in the family.
So THERE
