I just looked into this thread again, and when I looked back at my previous post here I realized that my tone may have been a little bit aggressive. Sorry for that. But aggression is actually something I would like to talk about here. That is one thing that could bring you in the right direction, believe it or not.
Many PUA:s go through a period when they after repeated failures (or lack of success) start feeling aggressive - they hate the game, girls, people, everything. Though they probably hate themselves for being such loosers, projecting their feelings to the outside world. I've been there, done that, and it actually turned me in the right direction!
My recommendation to you is to keep on going out, and fail fail fail until you can't take it no more. When you feel the aggression I'm talking about, go home, count to ten, take some deep breaths and calm down. The next time you go out you will probably be more prejudice than before, more cynical and more sarcastic. You will go into a conversation with a different attitude. You will be a slightly different person than before. In the beginning you may be a little bit too aggressive and frightening (overcompensating), but with time you will learn to find the right balance.
I don't know if this was a bad tip, but that was the process I went through, and it worked for me.
