Well, if you want to meet anyone, it's a necessary evil.
Strangers are friends you haven't met yet.
If you're out pounding the pavements looking for a job, every interview with every new company, the stranger you meet might be your future boss.
Social interactions make you nervous? It's a skill you have to master. If you have a job that involves any kind of customer service, you have to overcome that fear or your job won't last long.
Same thing if you want friends. As awkward as it might seem, sooner or later you need to break the ice, introduce yourself, and open up a little bit. By doing that much, you've increased your chances a hundredfold of making a new friend.
Trust me, it's not as scary as it looks.
