Boyz boyz boyz.
This is not an unusual problem in fact it's so common there's an entire industry built on solving it. That's why bar owners provide a bar and a dance floor. They pack people together, serve liquid courage and provide an environment conducive to sexual encounters. The problem with this is that everyone does it. Every guy is out there pounding back beers to work up the courage to talk to women. I seen a guy on keys once pounding beers in the shower! lol To become a PUA you have to be the exception to the rule.
The simple answer is that there is no answer. AA is something we all suffer from and you'll never completely get over it. The way I got over it was to escalate. I started out just approaching girls saying "hi you're cute can I get your number?" or "Hey wanna dance?" I always got rejected but that's the point. If you just try to get rejected then it doesn't hurt and you're emotions respond. I've been a PUA for over a year and I still run warm up sets there's no avoiding it. So when you go out STAY SOBER! Getting drunk makes you're approaches effective but then when it's time to actually get romantic you're fucked.
The Dance floor is a big tool I think too for over coming AA. When I go out I usually go straight for the speakers and dance around like an idiot. Instantly I'm the center of attention and my brain goes "well if I was trying to look cool I just blew it! Guess I can relax and have fun!" oddly enough that's the attitude you want.
As for gaming girls on the dance floor there's really only one effective technique. I've read lots and in my experience the dance floor is (like Mystery says) a trap. The way you can work it is if you bring buddies and have a planned dance. Me and some friends of mine used to go out all wearing purple and we'd line up to perform a planned dance. Instantly you and your friends are the highest valued males in the room and girls start opening you. You've now demonstrated alignment and social proof, confidence and a willingness to have fun. I actually just about scored with a Budweiser girl the first night we used this...... oh Budweiser girl I still miss you...... SORRY I'm back!
So when you go out start out maybe in another bar and run crash and burn game. Intentionally get rejected atleast 2 or 3 times. Then go to your desired bar and start rocking out on the dance floor. Don't grind any girls in fact push them away! If you have buddies rock out a planned dance and then head to the smoke pit or anywhere away from the music. By this point you'll be well in state and ready to sarge your ass off. Hope this helps boyz!
