The key to easy social interaction is to share common interests with the people you hang out with. This will make it that much easier to speak with them and enjoy their presence.

And because you are a college student, opportunities to meet new people abound, so you are lucky,...

The best way to proceed is:

• find a club/organisation which organises activities centered on subjects that interest you (sports, games, whatever)
• take classes in stuff that is interesting for you (like drawing, languages, etc). You will also meet people there.

Good luck!
