No idea. I was also always seriously picky, and only found something when I wasn't looking for anything at all. It's one of those terribly cliched things, unfortunately.

Do you ever have issues with self-confidence and the like? Because my standards tended to end me up pining after guys who were unobtainable - hindsight leads me to believe that it was a subconscious way to avoid really getting into something. Fear, maybe. I get along with guys really well, but as soon as one showed more interest, I'd freak out and starting thinking the guy had to be a lunatic.
