If the girl doesn't already like you, it's not worth talking to her anyway
that's basically what's been the massive shift in the community over the last decade or two.
It used to be about MAKING her like you.
'How can I get her attracted to me in the same way she's attracted to that good looking dude playing pool who she clearly keeps looking at and flicking her hair at?'
It was called 'attraction material' - ''I don't have good looks, so instead i'll make her attracted with my pushpull lines. I'll also tell her some DHV stories. Hell, i'll even open her with a neg to lower her value and make her chase! Dominant tone of voice!'' etc etc etc
But after many many years, people slowly realised it doesn't actually 'work' lol. People got results, but with girls who already liked them. The best still got rejected lots and they were looking in the wrong places as to 'why'. People were being fooled by randomness! (there's a good book about that btw)
Mysterymethod stopped being popular for good reason. People wouldn't abandon a theory on mass, no matter how cheesy, if it was getting fat old bald men regularly laid with 18 year old smokeshows. It fell out of fashion because people began looking elsewhere for something that would help them! (cue neuro-linguistic programming or mode1 etc etc)
Takes us basically to where we are now which is a more realistic stance. Effectively, outergame game is about not screwing up with girls who like you. It's basically flirting. But as we know from the age of 6, flirting is great when a girl likes you, and doesn't help at all when you flirt with a girl who doesn't like you. It's unwanted attention. This is the cold approach dilemma
With that in mind the only surprise to me is that people are still making a living as PUA coaches and stuff. Only a tiny percentage of people would actually benefit from it. You'd need to be someone who doesn't understand about things like eyecontact or soemthing! Nothing a coach can tell you is ever going to help past the very basics of being normal, which most people already are
