So one of the endearing qualities I found with my wife is that she called herself 'so-so' or 'ugly' in reference to her looks when I first met her... She clearly wasn't but she never thought of herself as anything great. I found she was really down to earth because of it and I immediately felt comfortable in her presence. Chicks who think they're hot are a pain in the ass whereas girls who got beat by the ugly stick try harder and I feel have better personalities. Hot girls are coddled by society, pedestalized, and treated better in general. They're always covered in makeup or fake nails and are obsessed with themselves. Look at Korean girls, most of them can't wait to get their first surgery and they never stop at one. I find that guys fall all over themselves to be around a hot chick, even a plastic one, while the ugly chicks takes a back seat and has to really try hard to win a man's affection. I much prefer the ugly girl mentality.
The trick is to make a girl believe she's ugly, I think that's what the purpose of negging is, was it not?
It's like the Elephant who grows up chained to a pole. If you take the pole away as an adult, the Elephant will still remain in the area because that's all they've ever known.
