If I had to start all over again(getting good with women), I would start from how this man in the following video did.
Just walking around women, and paying full qualitative attention to them.
I would pay attention to just about everything about women in my purview. The way they walk, the way they look around, the way they checked out other women, the way they dress, etc.
And I did that in my later years. Unknowingly, I developed an intuition about female gender, which is what all it really takes.
