In reality IQ matters much less than people think. The top 5 rated chess player of all time (Hikaru Nakamura) has a ~105 IQ. People with an average IQ are capable of performing at the 0.1% level with the proper structured training and time.
In my experience IQ mostly impacts the rate at which you learn things. So it took you 2 years instead of 1.5 to master a certain skill -- so what? As a society we should put more emphasis on hard work and results, and less on inherant traits.
