I'm probably shouting into the wind, but the common PUA approach messes with your head.
You memorize a bunch of routines but don't internalize the reasons behind them.
No doubt that, with practice, it might be good for getting laid, but it might also result in self-esteem issues or an identity crisis down the line.
Most of the OG PUA crew have huge issues later (See Roosh for a quintessential example who, went straight up alt-right nutjob born-again Christian.)
Neil Strauss, aka the author of the Game, failed to revert to "normal" after he went through his PUA research phase, and recently divorced his dream wife.
Anyway, that said, if you want success with women, at the very least, you need to have good inner game.
It has to be internalized - as in, basically you can do it naturally without conscious thought.
Self-confidence, banter, flirting, and the ability to connect emotionally. Most of these can at least be somewhat non-verbal.
That's basically what the PUA routines are trying to get you to behave like, but without the inner work.
Incidentally, the same skills can occasionally get you way better sessions...
