I never really think that I'm that far off from the average in a crowd.
But maybe that's because most people I hang out with are smart people like you guys.
I guess that's just part of how people choose their social circle, the ones that they feel that they are "normal" in. I have to say that I never really enjoy other people's attention, just because of the expectation and the stress that follows it. I like to be average kind of guy, doing average job, being at average height, almost average weight (in the US, that is...), average look, average income, average computer skill (again, average for the crowd that I hang around.)
But then there are stuff that I don't want to be just a fish in the sea with. Like my research. The thing that kept me doing research is that the topic I am researching might one day change the course of human life. Now that's some kind of accomplishment that you can't beat, and it doesn't really matter if other people are aware of it or not. The fact that I have an impact on the society is enough to get me going. That's also part of the reason that I'm still here.
Anyway, am I normal? I don't really know. I'm not without ambition, of course, but what's life without a bit of challenge, right?
