If you are good looking then you have the initial advantage of being eye catching, which is just the reality of the situation. Therefore, a good looker, will be 'fancied' initially on their looks alone, which is another reality.
However, after the physical admiration has worn off, then the personality is all we have left, so it is not a good idea to be swept away by looks alone!
My friend's mother always said "Don't be swayed by looks, they're all bald and fat by 40!"
I also remember hearing a tale told by Mick Hucknall (now he is ugly!) He said that he was going out with a fabulous gorgeous looking model and was completely swept away by her beauty. One day, he was listening to her having a bitchy conversation on the phone to her friend...so he dedicated the track "You're beautiful but boring" to her ... and dumped her!
