Be the person you wish you were. Anyone who doesn't like it is not a friend you need. It is absolutely possible to have a very active social life and also have intellectually stimulating friends.

I have long tried to make a point to never dumb myself down for the sake of others. The people it scares away are the people that I want to scare away, because they offer nothing to me and I probably offer nothing to them. And the people who appreciate my kind of intelligence are the people I want to associate with.

If it feels dishonest, it probably is.

Edit: Also, move to Silicon Valley. It's full of people who like smarts.
