Meeting new friends is an organic process. Follow your interests and the odds are good that you'll meet others who share them. For example, you might make new friends at the gym who share your interest in physical fitness.

I would trike 'meet a girlfriend' off your list entirely. Being in a relationship just to have one is kind of stupid. When you meet the right girl it'll happen and until you do there's no point in fretting over it.
