To be a man truly successful with women, one must first come to master his own feelings – to override deep emotions and instincts when he knows those emotions and instincts are going to take him the wrong direction.
Emotions are our snap, subconscious decision-making process, designed to be powerful to preserve necessary functions even in the face of logical decisions to the contrary. In today’s world, for instance, it’s easy to get caught up in life and feel like you have no time for children and can’t be bothered with offspring. But the entire reason you exist is that your ancestors all, every single one of them, successfully passed on their genes, and along with everything that makes you who you are, they also passed on the things that made them successful at survival and reproduction – some of those things being deep emotions that overrode logical thoughts like, “Eh, I don’t really have time for kids.” The desire to go condom-less in sex is one – spend enough time with a girl, and you don’t want to be wearing protection. That’s just one of life’s way of preserving the natural order of things and working to get you procreating.
But some of the things that worked in the past don’t work so well nowadays. In the past, if a man really liked a woman, fixating on her and obsessing over her and devoting tons of time and energy into getting her might have worked. In the past, beating oneself up over a botched effort with a girl one likes might have led to a man going back and figuring out a way to get her, against all odds.
