My advice is to stop trying to "network" in the traditional business sense, and instead just try to build up the number and depth of your friendships, where the friendship itself is its own reward. The more diverse your set of friendships are, the more likely you'll derive both personal and business benefits from your friendship later down the road. You won't know exactly what those benefits will be, but if your friendships are genuine, those benefits will magically appear 2-3 years later down the road.
