Pickmeishas won't understand since they are used to accommodating men's preference in a woman.

Men say they want a woman who is A. Men say they want a woman who is B. And most of the times those statements contradict each other; often they even come from the same man. This so called "logic" defies all common sense. Therefore it's best to not rely on this source of information at all.

And who even cares.

Yet Pickmeishas keep on trying nonetheless. They jump through hoops for male attention and validation. But somehow men don't want them anyway. Why is that?

I already answered your question: It's BECAUSE a Pickmeisha listens to men. No man - ranging from HV to NV - will invest in a Pickmeisha. It's stressful and simply not sustainable to do so.

A man wants to "secure" a woman. Probably because it makes him feel "manly" since it brings him closer to meeting his biological purpose. A woman with high standards might annoy LVM because she indirectly confronts them with their own laziness. Nonetheless even they want her because her high standards provide peace of mind. Men are afraid of other man stealing "their wife" (or gf. But for the sake of the argument I'll stick to "wife" as it gets the message across better). So no man, especially the HVM who has a lot to give, will give to a Pickmeisha. Understand that a man wants to invest in "his wife". But he knows that if you settle for crumbs of one man you'll settle for crumbs of another man as well.

High standards convey the following message:

She thinks for herself. She can't be be easily manipulated by other men. Her standards are high but absolute. I can meet them if work hard enough. Other men are less likely to get where I am, because she doesn't give herself away so easily. (Note: This is the reason why men don't respect "easy" women and call them deteriorating slurs like "hoe" and "whore". Yes, this applies to liberal men too, they just want you to believe that this is nothing bad so you sleep with them regardlessly.). If I have to work to get there other men have to work just as hard and in the meantime I can fend off the intruder. She takes no bullshit from anyone. If I don't meet her on her level she'll find someone else who will. And I actually like this.
