Amen. Do not go to the vapid parties, but do go to parties. Learn to throw the parties yourself if you have to. They don't have to be big at first -- a lot of the best parties I've known had less than a dozen people.

I assure you that somewhere, somehow, there are groups of non-vapid people on or near your campus. Find them. Try clubs of all sorts, film societies, drama clubs (cast or crew!), amateur sports, music groups, anime or SF conventions... whatever. Just find them.

You don't find girls at parties. Truthfully, you don't WANT to find girls at a party. Any girl after the first month of freshman year who will hook up with someone she met at a party - has already done so. The best route is to find an activity that you like and meet people through that, then you actually have something in common and a chance to spend time talking sober. That forges real relationships, which ultimately are a lot better because you have someone to lean on not just someone to hook up with. But truthfully, having someone is important and hardly precludes you from being in a successful startup. There are 20 of us now at my startup and only 1 or 2 are single.
