Unrealistic expectations of what you can accomplish points to a lack of self-knowledge.
Difficulty in dealing with average people is a social skills issue, but 'average' and 'below average' people might have that same problem.
More likely to question things and annoy people in the process is again a social skills issue, really clever people can work out lots of stuff without having to ask for it, and when they do it's a matter of timing, tact and packaging.
Less likely to accept traditions again has nothing to do with IQ, but if you are smart you may be better able to argue for yourself why you do not wish to follow traditions. To be in other peoples face for not accepting traditions would be another social skills issue.
Less likely to enjoy the simple pleasures in life is not at all limited to people with high IQ.
Less likely to find a job as an employee rewarding depends on what you define as an employee. If you think a full professor at a university is an 'unrewarding' position because you are an employee then you probably have other issues.
Seriously, I can't see any of those problems related to having a high IQ per se.
