there are countless examples of ugly/fat/short men with good looking women. women don't fall for looks alone, but rather status/behaviour/personality. It's all about that when you meet them. The more evidence you present that leads them to think you are of high value, the higher is the chance of scoring. Nothing revolutionary but these PUAs have put it in a system for other to learn.
PUA may not be the magic pill, but I think it helps/inspires some people.
