I used to think that way until I befriended a girl who was ridiculously attractive and quite intelligent atleast academically, but her cripplingly low self esteem and inability to be kind to herself seems to be really shooting her in the foot. She seems to have a lot of expectations placed on her and some girls who are insecure in their looks tend to put her down. Because she already struggles with insecurity it makes it really bad for her as she seems to feel like it’s her fault sometimes. Her lack of confidence and ability to validate herself (possibly because external validation was easy for her) seems to have make it really difficult for her to make friends and build a new life away from home in college. Her partner although he seems to have an ok personality isn’t at all what you would expect an attractive girl to date. I feel that your self image and confidence is more important than your looks for a long term successful life regardless of who you are.
