Yesterday I had to share a lot of my PUA knowledge in my university, not because a couple of guys wanted to know, and neither because I was in trouble and had to share my techniques. No, I was in a psychology lectures, and the whole lecture was about the art of communication, I was the only one who answered in that class, because everything that the professor mentioned I had already learnt from Mystery, so every  time the teacher asks a question lie "Does anyone think they have an idea what the meaning of rapport is?" I would give her the proper definition, at the end of the class, we also watched a seminar by a PUA I forgot his name but it was about body language and how to use it to be mysterious and trigger friendliness. Sure, being natural is important, but keep in mind a lot of these techniques are scientific, so use your logic when using them.
