PUA and practical 'game' seems to me to boil down to how to project confidence when interacting with females. Anything much beyond that and the PUA is either up his own ass, trying to sell you something, or at best, telling you how to spend hours mastering a technique that might up your 1 in 50 success rate to 1 in 49.
My biggest problem with following the PUA lifestyle is squaring the requirement of confidence being crucial to making her gina tingle, with the avoidance of turning into a desensitised brute after repeated rejections. Posessing confidence might not be strictly identical to being a 'bad boy', but in order to maintain one's 'state' after multiple rejections when gaming, I can't see any other route but to become utterly disinterested in what a female thinks - in other words, just see her as another pussy that you are trying to get into.
This relates to another common theme on this blog - the Trauma Myth as a justification for draconian punishments for men who break statutory rape laws and other feminist sex rules. A man is committing a heinous act which deserves to be punished mercilessly if he has sex with a girl a day under the age of consent, because such a girl will be 'traumatised' for life as a result of being 'abused'. In particular, this trauma is often said to entail that the abuse victim will find it 'difficult to maintain relationships' in the future.
Fair enough, if this is an inevitable or even likely consequence of such crimes, then the man does indeed deserve to be punished harshly. But something I've never understood is what this supposed subsequent inability to maintain relationships means. For a man has to take the initiative in virtually every stage of a relationship and the pursuit of the opposite sex. And his likelihood of success in securing and maintaining any kind of sexual relationship, as PUAs tell us, is mostly down to confidence. The woman essentially just has to decide whether or not to open her legs, sleep with him, live with him, stick with him etc. In other words, in terms of being able to maintain relationships and have a successful love life, the psychology of a man is far more fragile and essential than that of a woman or a girl.
If the Trauma Myth was true, and the real basis of feminst sex laws, then in a fair world, when a female sadistically rejects an approach from a male, where the level of rejection far exceeds that which is required to express disinterest and 'NO', and whose apparent purpose is to harm the man's self-confidence and ability to approach women in future, then she should be guilty of a crime as serious as a sexual assault or sex with a minor. She is deliberately harming a man's ability to succeed with other women. There is little ambiguity about that malicious intention, whereas when a man sexually assaults a woman, or has sex with an underage girl, the intention is rarely to actually harm the female, but simply to obtain illicit sexual satisfaction. Furthermore, in most cases of these inflated feminist definitions of abuse, the resulting 'harm', especially the 'inability to have relationships', is largely speculative and unproven (aside from femi junk science), and probably a result of being labelled and victimised by the abuse industry if it does occur.
As relates to practical PUA advice for the beginner (as I am, after a long time away from 'game'), the important lesson is to go slowly and progress at your own level, building confidence gradually and realistically. A popular technique is to begin by asking women for the time, or for directions, before slowly graduating to making real approaches. If you're really short of self-confidence, it would probably be better to avoid approaching women in the street altogether until you have sorted out your underlying confidence issues. The possibility of encountering a sadistic bitch who will take pleasure in 'scarring you' is just too great (the possibility of this is even higher if you make the mistake when a sensitive beginner of approaching girls in pairs or in groups).
