Potential problems:
* unrealistic expectations of what you can accomplish
* difficulty in dealing with average people
* more likely to question things and annoy people in the process
* less likely to accept traditions
* less likely to enjoy the simple pleasures of life
* less likely to find a job as an employee rewarding
What are others?
It is only difficult to deal with average people if you believe yourself to be above them and look down on them.
You only annoy people by asking questions at inappropriate times, if you were really that much smarter then you would know when to ask and when to shut it.
I don't know how you would measure the acceptance of traditions but off the cuff Stanford, MIT and other places where high IQ people tend to congregate seem to enjoy their traditions as much or more than more middling schools.
Sounds like a personal problem.
Nope regular joes find work boring too, just look at all the pulp fantasy stuff made to distract the common man.
The main problem with a high IQ seems to be it is easier to fall in to a narcissist trap of thinking you are somehow different from the common man just because you can add a little faster.
