I got some theories behind it, if you want I can explain more.

Ok guys, here's my "system".
You might hear some things you already read in books or heard, but I'm going to explain how my system worked that day which was without the acknowledge of PUA world. (when I say system, I mean my mindset, my mind's operating system)

Some pre-story:
So, I planned to go out beast mode because I wanted to get to know a girl on my class. I thought "what a better way to introduce myself using the lesson as an excuse?"
I didn't have pickup lines, or tricks from Mystery, I just had some kind of ideas. The basic idea was "you got to put your ass over there and get to know her"
So I asked her if I could take the seat near her and she said yes, before lesson started, so I just left my bag there and went away to go to talk to some friends. I came back and found out that the blondie shifted two seats away from me, being substituted by her twin (girl) friends. I thought "shit! this bitches just stole my chance" so I decided no matter what, I was not going to come back home empty hands cause I was turned on. So I decided to play my game with the twin sitting near me, hoping I'll get to her friend one day. (Nowadays idgaf about her tho)
Now here's the funny part.

How I set my system to beast mode:
Woke up and got dressed properly, not too classy, but kind of classy.
Then I went dynamic, which means my thought were almost just positive and my movements were fast. This might not make sense to most of you, but you know, I live with this status and belief almost all time which is that everybody need to have their own speed in movements, thoughts, way of speaking and if you go too fast or too slow, you just lose control of yourself. I had control because the first thing I did that day was reminding myself what my life timings and speed were. These values are and were fast enough to had me going like "boom, I'm unstoppable" and that made me super confident that day. Also music helped me getting that fast way of thinking. So I went there and used a pickup line even though I didn't know it was a pickup line, and that girl just agreed to let me inside of her mind. We got to a point where I switched from asking her what high school she went (and other basic stuff like that) to doing the fb trick and showing my computer and web skills. It was then, where I felt some fire inside because I was explaining things I worked my ass for (in that case was the hacking method) so this passion was the key to getting her attention really high. It was on that point where I felt like I had her under control, simply acting smooth, feeling my brain speed right, and all those personal values I've got. One of the main thoughts to win over her was "play it striking fast, without giving her time to think or say something smart that might turn me down, if I don't strike fast and score she'll do it"
So when I wanted her to shut up and turn to her twin sister, she'd get it. When I wanted her to look at me without even telling, and to turn red on her face she'd do it. Basically I worked on my internal way of acting and thinking, I build up some hype and found my timings, then I studied her, waited till I'd get even the most small signal, then strike fast and piece by piece take over her mind.

Juice does not worth to squeeze IMO.
