"do they just get to know hot looking guys?"
Hot women are approached nonstop all day long with compliments and people kissing their ass etc, after a while of that happening it becomes sweet but boring. They are flatttered but frustrated - "Why does every guy I step into an elevator with comment on my ass"
With the fact that they are hot, some of that comes from having good genes; however, if they are truly attractive and put in effort to maintain themselves, you should do the same to stand in their presence (this is the mindset of an attractive individual). Why should they put in effort to look good when someone else doesn't even try.
Some of those attractive women are "done" trying to find a good guy that is confident and as such they lower the bar- but with that being said, you should be all the more motivated to win the girl over that you like. Don't look at road blocks or competition - just identify what you want and shoot for it, who cares if they are a bitch- that's where you move on and say "your loss" *smile*
To have more success with attractive women:
1) Join a gym and become attractive yourself
2) Take things lightly, they are only putting up a front to scare away phony individuals
3) Tease them back, nothing is fair in this world
4) Use humor to an advantage to maintain their attention
5) Be interesting, do things - be busy etc
