You're missing part of the story here. You have the right attitude, but unless you are some kind of Chad, you don't just stop trying and suddenly have a bunch of girls trying to pick you up. You are either still cold approaching, and maybe even getting numbers, but not pursuing (in which case you have already expressed interest). Or you are putting yourself in situations where there are a lot of women around to interact with (either by happenstance or intentionally).
If you really didn't care at all, you wouldn't even bother talking to them. It's like some guys here, they say their method is to ignore women and they come out of the woodwork. But that doesn't really explain what they are doing. To do that they have to be displaying high status at the very least (unless they are Chad, like I said).
I'm definitely no "Chad", even though I'm not ugly I don't think I have the stereotypical looks to pull by that alone. I do not ignore women or sit passively thinking women will approach me, that's stupid and technically still trying if done solely for that purpose.
With me there's an absence of trying, not the opposite of trying. I'm talking to both men and women, without necessarily trying to accomplish anything and sometimes that just naturally turns into a thing. I do talk to strangers, but calling it "cold approach" is a stretch because it implies I have a particular intent which I never have at the point of opening a conversation. I take up some space when I'm present, I don't go unnoticed. Again not an intentional game thing, I know it has an effect, but I am that way regardless. I don't shut up, I engage in any conversation around me because I'd be bored out of my mind if I didn't.
There are still a few times where I have done literally nothing to be noticed and some woman approaches me, no clue what's so interesting at first glance. Happened just a few weeks ago, spotted her across the floor in a bar as she was heading directly at me. Sat down next to me and bombarded me with questions about myself, wtf?! I had been sitting there calmly enjoying my beer, watching idiots who can't dance and enjoyed the music. Literally nothing and I'm sure there was better looking dudes around.
Maybe I display status somehow, maybe I've internalized my game so much that I've essentially become a natural. I just do what I do, have fun, mess with people and enjoy every moment I can without much thought. But yeah, most of the time I'm making myself noticed by just being who I am, it would be harder for me to sit passively and shut up. I'm just not intentionally approaching with a goal in mind or act as I do to try to get pvssy. Women approaching me is the natural result of me being carefree and enjoying myself. I never go out trying to get women, I go out to socialize and have fun, if I do that I have a good night and it just happens to be attractive. That's a win-win situation, no effort, having fun and women coming at me.
