Your IQ score only matters if it's below a certain point. If you're IQ is 100 or above it doesn't really matter. All IQ measures is your ability to take standardized tests and your capacity to hold information. It doesn't measure your intellect, wisdom, or how cunning you are, which all influence your overall intelligence (or how we think of intelligence).
For an example, in 2000 the person with the highest IQ in Texas (over 180) was a motorcycle cop. IQ is potential, not application.
