Just gotta throw caution to the wind my man, and simply meet as many people as possible. That's what college is for.
Don't got out looking for anyone, but go with the flow, and I guarantee you'll meet someone awesome one of these days.
I'd stay offa those dating sites. I know more than one couple that have gotten married from OKCupid, and that's great for them, but I can't imagine going the rest of my life answering the question "How did you two meet?" with "the internet."
Every relationship needs a great story. Get out there and make one happen.
