PUAs teach you that cold approaching is okay when it's not. The students go out and practice cold approach and fail then come back and think the problem is their "game". Then they come back and watch every video teaching them how to improve their game which might even be telling the truth but they aren't even getting to the point where that game is useful to them because they're still stuck doing a failed approach method.

When you do a warm approach it creates feelz and creates a real fantasy story in her head. When you do a warm approach the majority of 'game' was done in the prior eye contact. You show much more confidence than doing a cold approach and you've already validated her through eye contact in order for her to be receptive.

When you do a cold approach you're just another chode in the club trying to put your penis inside her and it's also a mystery why you're talking to her unless you have the game to pull it off, but even then you have to face much more obstacles.

Deep down women know why you're approaching them but you have to be very blunt with your intent in order for them to reciprocate because they are very afraid of rejection. This is why warm approaches are much better because simply through eye contact you eliminate all these obstacles and if you spark feelz in the both of you it's ez money.
