How do I become more social?

Oh hi again, I am clicking on any questions that are popping up in the side bar right now, you are being a busy asker!
Go and try to talk to random people, that's how I met my current girlfriend. She was sitting in the chair next to me, looking pretty lonely, so I just struck up a conversation.
Say hi to random people if you are out for a walk and happen across another person. Say it with a smile on your face! People typically like being acknowledged. It lets them know that some body cares, even if only a little.
