I look at IQ like a glass to hold water. Some of us are born with shot glasses like George W. Bush, and some are born with giant beer steins. The size of the glass isn't as relevant as how much you actually fill it.
I've seen some people who weren't given much of a glass, but they worked very hard to fill it to capacity. They are much better educated than someone who has a large glass but who is too lazy to fill it up so they've only got a shot glass worth of water. The size of your glass isn't as important as the amount and quality of information you fill it with.
I'm not very impressed with high IQs. I only mentioned mine in response to someone else's. By the time I was 6 years old I already knew algebra, had read the dictionary, and other books, etc. My school began testing me like crazy. I was in the counselor's office more than the classroom during my first year, and I tested higher in 1st grade than any of the 6th graders in my school.
The school district wanted to move me from 1st grade to 8th grade, but my parents wouldn't allow it. I believe this was a mistake. I was bored all through school learning and re-learning the same material and as hard as this is to believe, back then I was a trouble maker; a rabble-rouser.
