let alone some average looking guy who happens to be confident and has nice clothes on
Maybe that's how you classify yourself, but I don't put myself in that category.
And where did i mention confidence and nice clothes? I'd hope that you don't think that this is the only key to getting the really hot girls?
Go to the clubs and yes, you'll find the 9's and 10's have that attitude. Do a cold approach in some random location and yes, you'll find that attitude. (they put up the front to keep you away, because you're not worthy. If you are truely excellent, the shield will go down and most times, never even be up in the first place)
Meet them as they come along, through friends, work etc... (normal situations) and you will never get that attitude... unless you are just an average joe who makes it blatantly obvious he's trying to cut her down a few notches to his level.
