You know, the ways I've gotten the method and system set in my brain are two things:
1. I've been explaining it to my buddies, and the more I repeat it to them, the more I ingrain it in myself
2. I practice on my friends without them knowing. When I'm sitting at lunch with some people I know and there is a girl I haven't met before, I game the shit out of her, and let me tell you, its SO much fun.
Think about it, when you learn to ride a bike you put on training wheels, right? well, you can specifically choose situations that will help you ease into the big world of PUAs. I went to a frat party where I knew half the guys in the frat and I knew half the girls. I walked in, hugged/high fived/cheek kissed every person I knew on the way in. It was like practice with training wheels, I displayed so much DHV the first minute I was in that place that basically every girl in the room met me by the end of the night. (I # closed with some girl who calls/texts me a bit too often...but I can deal

)
yeah, practice on friends, explain to your guys friends (they can only benifit, right?) or a specific guy friend, and then put yourself in situations that make you feel confident. Inner game is huge.
