Which is to say that half the battle is putting yourself in circumstances where the environment around you is helping your odds of attracting someone.

If you meet a given person at a destination wedding, there's a much greater chance of hooking up than if you met that person at the DMV.

It's also why being a passport bro/chick or a dater of one is appealing. At least one of you is in a different country and probably more receptive to new and life changing experiences. As opposed to the daily grind in Western countries, where people are just going from one shallow experience to another at a frenetic pace.
