I learned many many times that... nice guys finish LAST yes.
You seriously have to be a dick head to get a girls attention.. then when shes hooked you can be your natural self.
But I find this only works with chicks under 30 After that age they tend to not want that cocky, prick asshole type.. they actually do want a nice guy because they were treated like dirty ho's their whole life!
Sam said it rite, should have made fun of her, would have gotten you farther.
