The trick is to get out there and do stuff. Choir, martial arts, swing dancing, medievalism, what ever floats your boat. I met my first wife at work and my second (who turned out to be The Love of my Life) at a contemporary pagan festival. Pro tip: guys, if you have a passable singing voice choir is literally the best place to meet women, in part because the women always outnumber the men. This is especially true if you are a teenager.
