Before I declare my opinion on the matter, I'll tell you my own little high school story.
I finished high school about a year ago. These years were some of the worst in my life. I spent my freshman, sophomore, senior year going from one therapist to another, while at the same time, I didn't know if I would find my mom alive when I returned home (because of my dad's anger outbursts, then her drunk boyfriend's).
I was considered a pretty girl. I don't want to sound conceited or anything. I just want to get to a point. Yes, I did get attention from guys, but not the kind you'd want to get. Nobody actually treated me better, sometimes they treated me worse than less good looking people. I was really quiet throughout the whole school year, hardly able to make friends, and stuck to myself most of the time. I was very reserved and thought high school was a hell hole. I even dreamed of crushing down in a lot of terrifying ways. I just hated it.
I was bullied quite a lot. I was sexually harassed a couple of times by two guys in my class. They got away with it and no one did anything about it. I had made friends with a guy from my class, who was a looker but also the quiet type, and we got romantically involved but it ended tragically after he had to move far away. He wasn't popular despite his looks, and now that I think about it, our relationship would probably go downhill since we both were depressed and had complex thoughts far too often.
In total, so far, I've never won in my life because of my looks. Nor will I ever. There was a girl in my school, who was very popular, but she wasn't considered pretty. Still, she was terribly outgoing, easily made friends with people, and had a happy and smiley attidute that attracted people. Her boyfriend was the most good looking guy in the school, and she broke a lot of hearts on the longrun, I would know, because one of my friends, who was a guy, had a crush on her the whole time I was in school. Same goes for other guys in my class.
Looks are important, yes. I won't deny that they are not. But they are certainly NOT everything. The 70% goes to one's attidute, personality, and way of interreacting with other people. I'm not just saying that. It's been prooven. A very pretty girl could be much more unlucky with her social life than a girl, who, even though not pretty, knows how to handle social situations and charm people. And remember; charm is something everyone is capable of obtaining, good looking or not. And sometimes it's charm that makes someone attractive, rather than good looks.
