Socializing is important, even if you are in the 99.9th percentile. You just have to choose your peers more carefully. When people bore, annoy, or misunderstand you, do move on! Keep looking for people in your Window of Comprehension. The odds are slim, but far from hopeless!
It starts in early childhood. When you have highly intelligent children, don't make them spend time with peers they don't get along with! It would only lay the foundation for a life-long sense of not belonging anywhere.
At school and university, actively look out for people who are on the same intellectual level as you are. Do not make too many compromises! Of course, there's nothing wrong with giving some slack to someone whom you really like, but stick to your principles! Do not try to "dumb down"!
On social occasions, it might be wise to adapt to the pace of the masses. Make a deliberate effort in such situations! Use your intellect and willpower to adjust. It's only for a limited amount of time and you can wind down afterwards by reading a good book about quantum mechanics or statistical modelling! ;)
Later in life, consider joining high-IQ societies or at least attending their public meetings. They offer a much more interesting sample than the general population. Take your time! Even in high-IQ societies, finding someone might take a while.
Generally, don't talk about your IQ. Most people will only get annoyed, pretty much nobody will be impressed or sympathetic. On the other hand, it can be used for a quick-check: be blunt and see how they react. Highly intelligent people (≥3σ) will often be interested rather than offended. (Of course, this works best with people you can easily avoid afterwards, should the need arise.)
Do look for work that keeps you in the flow! Bore-out is real and it is hell. Given the job landscape out there, this might very well boil down to working part-time and looking for something interesting that you can do on your own.
Fortunately, we live in an age where there are options for highly intelligent people. It's still not easy, but it gets better. Remember: the most important thing is to connect!
