From one extreme to another. I understand not to give a girl too much attention. That's obvious, BUT:
Ignoring girls is great, but won't get you results unless she has a high enough interest in you. I've see a fair number of these threads where the concept is ignore the women and they'll run to you. It's annoying.
Sure the game would be changed overnight if all men ignored all women. But it won't happen. And besides, not all men are attractive. If a girl is to talk with a hot guy and ugly guy, and neither gives her attention, hot guy wins.
So you have to try eventually. Ignoring and giving little attention is only part of the puzzle. We all can't ignore women entirely and then a group of Victoria's Secret Angels will let us destroy their vaginas a week later. Guys that give attention for free are a dime a dozen, and every girl's iphone has numbers for this purpose.
Your value brings results.
