Danza, I disagree with the statement that being confident doesn't help if you're below average looking.
I may have believed that once upon a time.
But from own my personal experience and from observing others in real life, I no longer believe that as true.
Genuine and high internal self confidence (i.e. not a flimsy, superficial confidence nor a narcisstic over-inflated ego) in 1 or more life areas e.g. career, social life, etc. is a HUGE benefit to anyone no matter where they fall on the scale of looks from 1-10.
On the flip side, even if you're average/above average in looks and dress impeccably; sadly your lack of genuine self confidence and anxiety in social situations soon overshadows this. I'm speaking from personal experience.
Fortunately, my looks and dress sense improved significantly over the years (and people did notice) but my low self confidence and social anxiety (not looks related) remained. And that quickly drew people away. Therefore, in the end nothing really changed for me
At least, I can now confidently exclude physical appearance as a 'reason' for why I'm a social outcast and have a massive phobia of public speaking.
I believe we should all keep our appearance tidy, look after our bodies and be hygienic but beyond that- a below average physical appearance is not the cause for a low self confidence or for being unable to fit in socially.
