How can somebody who's a sportswriter be afraid to talk to people? In your job, you're required to go up to complete strangers and ask them personal questions all the time ("What were your emotions?" "What were you thinking?" "Why did you do that?")
Yet, you can't hold a beer at a crowded party and talk sports or movies or computers or school with folks you at least kinda know?
If you can screw up your courage to do interviews, you can socialize on a college campus, where you already have much in common with everyone else -- you're all going to the same school, taking many of the same classes. A little conversation about that can reveal other common interests. You just have to take that first step and scratch the surface, after that it snowballs.
