Sometimes people over-estimate their confidence in something and crumble from their delusion.
Other times people are either arrogant or mask their insecurity behind a veneer of confidence like someone mentioned.
Who knows what women are attracted to? I read in a study they were attracted to hormones of a man. This study was interesting as they gave the women different types of dirty clothing (i.e., the man didn't take a bath and was wearing the clothing for a few days), and the women attributed their attractions to the best "scent", of course they didn't know about smelling clothing that hadn't been washed or changed for a few days.
At this point, I don't care anymore about what women are attracted to. Either they like me or they don't. There is a lot of women and less men in the world. So who really has the upper-hand here?
