Starting from the very beginning, from the fundamental principles, from the evolutionary caveman type shit. As Elon Musk says, if you're ever trying to understand something, forget everything you know or assume about it, and start from the very beginning to weed out the fundamental truths.
1. evolutionary psychology
Caveman type shit. Because 20,000 years ago is where our instincts still think we are, completely unaware of the the pill, abortion and the sexual revolution. So that is where we shall begin.
2. differences in male and female attraction
Females and males look for very different things when choosing a partner or mate. Most probably subconciously. Relates back to the caveman type shit but also how it's essentially the same in the modern day too.
3. it's a skill like any other
Most guys don't realise that talking to girls, sleeping with them, dating whatever, is a skill like any other. It can be learned and improved. So no matter who you are, you can learn and get better at it.
