Jessica alba lookalikes? I figure that if you have a freakin' hot girl, some other guy's gonna want her off you. I go for a girl that i can see beauty in, though they may not be the hottest girl in school, they're still hot.
The thing i don't get, is people say the go for personality over good looks. Would you go and talk to a chick that looks like she'd ben hit in the face with a shovel, with the hope she has great personality, makes you feel great, and try to hook up with her? I know i wouldn't. I talk(ed) to the girls that were hot (not all the sluts who are just constantly up for it) and i might actually have a chance with. Then, if you talk to somebody like that, then find that they make you feel amazing, hold nothing against you, and you feel you can be yourself around them, then go for it. I figure that's how it works. or wait for the freak chance some real hot girl is obsesse with you (it happens - more to some than others, but it does)
I am not the best looking guy either. With no false modesty, I'm not ugly... Apparently i have nice eyes though. Chicks dig that. Apparently.
Moral of the story - It's all guesswork. Keep waiting, you'll find someone truly amazing eventually. Trust me.
