Okay, not really. But quit doing things just because you think they'll help you get girls. Usually, the exact opposite (ie, not giving a shit) works better.
For example, I was grabbing a beer with some friends, and while waiting for our next round at the bar, I noticed several hot girls stand beside me to order while casually making conversation. There were several other spots they could have stood as it was a Wednesday night and the bar was next to dead.
I forgot to mention I was wearing a grey sweatshirt and a 2 month old beard. Maybe these chicks just happened to be into guys with beards. Maybe they dug I wasn't wearing a gay muscle shirt. Or maybe they were just horny and I seemed a sure thing.
It's happened to me several times in the past. I don't dress nice. I dress comfortable. I don't care about gelling up my hair or shaving or anything fancy. I don't even wear shoes, choosing flip flops instead.
And girls come talk to me. I can't explain it, but I know that when I shave, comb my hair, wear nice pants and shirts, and shoes, I have to go up and talk to girls. And I notice that the reason I do those things is because I'm planning to go talk to girls.
It's when I don't give a shit that they talk to me. Then my instincts take over.
