Not that I know this from first hand knowledge, but I’m guessing persistence pays off when it comes to “The Game”.  I was always the timid guy around the girls that got way too dejected when I got shot down by one.  I would crawl back into my hole immediately afterwards, sob in the corner, and re-emerge a couple of months later, only to repeat the cycle.  It was a vicious cycle of pathetic-ness . . . uh yea, patheticness is not a word, but I think you get what I mean.  Anyways, I hear guys with confidence and thick  skin that are persistent, get results.

On a side note and based on my own experience, I think just not being afraid to be yourself works wonders.  You’ll find some one who’ll like you for you.  Ah, I was feeling preachy.
