I dont think i can do these formulas anymore...like when I am talking to a girl, my mind is so occupied with all these pick-up rules that I cant think.
someone told me "just be nice, but not too nice, and girls will come to you"
I dont know, maybe I should just be myself.

As I mentioned in another thread, I have a few friends who I'd categorize as average looking at best and they pull women. The common denominator between them?

-disarming demeanor (if you are concerned that you're coming off as a creep, chances are you'll project this and actually come off as a creep)
-don't used routines, instead focus on present and let the conversation progress organically
-don't rely on canned material, in fact typically they 'open' with a "hi, how are you?" "hey, you look bored thought i'd come over and talk with you" or some sort of observational comment within the environment such as being in a clothing store such as H&M and asking the girl beside you what she thinks of the hat you're trying on.
-are engaging AND enthusiastic

Biggest thing of all? They don't let rejection hold them back. They simply don't get caught up in the WHYs of being rejected. Instead, they simply move onto the next chick.

what do you mean by disarming demeanor?

They don't come across as threatening. They approach a girl from front, not back, they don't get all touchy with them, they smile, and come across as being experienced in talking to women (which only happens with practice).

If you're still juggling rules and routines in your head, you haven't broken down pickup and practices any of them enough to internalize them.

Routines and material really do work. Before I knew anything about PUA, I would use the same jokes and openers all the time. I just didn't know WHY they worked. The point is, these were already a part of my natural personality. The stuff I've learned since coming upon PUA has reinforced these traits, but I had and still have a lot of learning to do.

What I suggest is that you take the weakest part of your game, be it opening, comfort building, and go out a few nights a week and just focus on that until it becomes second nature. Practice it to the point that you could be having a cellphone conversation with your mom and STILL pull off the material.
