Genetics doesn't stop people from trying to get better jobs and/or make more money, just because they don't have the born brainpower of Stephen Hawking. Everybody has to make do with what they have, but don't use it as a crutch. I've never bothered to find my IQ because it doesn't matter. If I tested low I might lose motivation and not work hard. If I tested high I might rest on that and not work as hard. I'm going to try to be the best I can be regardless.
