Yeah, this PUA stuff is a bit too much. The best way to approach things is to be to calm, fun, and friendly. Also doesn't hurt to try some humor. That's really all it takes, I've found.
You can certainly pull off negging, sure, but I think for that you need to be VERY confident before you even do it. That kind of skill requires prior practice and experience. People often misinterpret the "Don't be a nice guy" into being a jerk. NO! It should really say "Don't be a PASSIVE guy," because that's what the problem actually is.
Its good to be nice, polite, and kind. Any girl who doesn't appreciate that isn't worth your time. HOWEVER, don't let your politeness scare you away from making your intentions VERY clear to a girl.
This post isn't really directed at anyone, just a culmination of everything I've been thinking since reading the last few pages. Good luck to guys like
