It's also the reason why most people are less popular than their average friend is, even though they are (on average) as popular as the average person! Since popular people are on everyone's friend list, but unpopular people are only on a few friend lists, your friend list is biased toward popular people.

As someone that has more friends('popular'), its all a matter of effort.
I go out every weekend, I talk to everyone, I ask everyone for follow up contact info.
Yeah I get turned down probably 50% of the time, but its a numbers game. Sometimes you meet incredible people, but its taking that first step that matters.
Anyway, if you want to meet people, always go to events you are invited to, meet people. No one remembers how a conversation starts, people that are weird about communication are forgettable.
