For a guy, obviously her looks count as the major factor to become physically attracted to her. There must be something physical about her that DOES IT for a guy! Then, as you are getting to know her & you find out her personality this will keep the attraction, & dating alive, or not.
Now some guys, even though they may have scored a stunning beauty, but she is a little bit bitchy for some reason or other (& she uses her looks, as she knows she is sought after by many other guys) just don't see past this physical attractiveness & strive to bend over backwards to keep their beauty satisfied, giving in to her demands & giving her anything she wants. BIG MISTAKE!
So to conclude, her looks will usually get the girl, then her personality is what counts that keeps him interested. Where her career is concerned, read the above again.
