In all honesty breh, social skills, body language, charisma etc are not things that can be taught
It was skills people naturally developed. It’s lacking nowadays because people socialize way more online than in person. That led to the social awkwardness that made these traits more rare.
Main thing standing in a man’s way is his own fear of rejection. The fact dudes want to know what’s the perfect way to talk and act to have a sure fire way to bag women is rooted in the fear of rejection. Wanting to know how to have a damn near 100% success rate is rooted in the fear of rejection.
I believe it CAN be taught, but doing so would upset the social order of Hypergamy
