Often the more you read, the more confusing and uncongruent you're thinking will become, more so if you're just starting out and don't know what actually works. Every method is created by a different person using his own style, and a lot of the principles and beliefs in these methods are conflincting. For example, Gunwitch writes:
Reading her palm, doing a psychic "cold reading", doing a handwriting analysis, playing a game of some kind ARE all LOSER behaviours
Whereas this is an integral part of other PUAs game. So in my opinion, you should ideally have one core system to base your game, but add your own style, and incorporate other skills you learn into that. Make it your own, that's one of the most important things.
