Stop being so corny and walking on eggshells around women.  The whole pua community up to now has been based on avoiding rejection and formulating some sort of advanced skill set that doesn't exist.  rejection will always happen and you can see it for yourself.  take the most advanced dude you know and have him do 100 approaches in front of you,  he'll get rejected the overwhelming majority of the time and he will only hook up with a very small percentage.  the reason you're anxious is that you have performance anxiety,  stop trying so damn hard and you'll see how that anxiety goes away.  simply approach and have a flirt.  don't get stuck in your head thinking about what a false pickup artist told you.  Man up,  approach and deregulate and inject your personality into interactions,  see how that works out for you before trying to be a gimmicky dork.
