A lot of guys, especially shyer more inexperienced guys, have a perception on meeting women that goes like:
Hot Girl is With Her Friends----Guy Walks Over----Girl is initially disgusted or simply neutral----Guy spits his "game" and she softens and gets attracted-----They go home together
There's a problem with this and it's not that it doesn't work. It's that it's not a constructive use of time or energy.
See, there's a need for selectivity when the resource in question is so large that no one could actually try all of it. An important fact to remember is
There are so many single, available and interested people to meet that you will never ever "run out"
So then the question becomes how do you justify talking to girls who aren't interested in you or are neutral? Furthermore, how do you justify bypassing interested girls for neutral or disinterested girls? You can't. The problem is with the formula above. You know the formula and so you're looking for the x variable, which in the formula is the disgusted girl for you to charm. Then, you're confounded when it barely works.
I've slept with a lot of girls and the truth is I never really talk to girls who aren't already interested in me"
Notice guys whom a lot of girls find really attractive. Notice how they don't actually spend a lot of time convincing the girl of their worth. Yes, they may spend time convincing them to sleep with them even though they're an obvious dirty player but this is with girls who they know find them hot. Sure, it's a snowball effect for guys. When you start sleeping with some girls you feel confident and other girls naturally are attracted to this and/or there's the harem effect where all girls seem to want the same guy but the fact remains convincing a girl who's not very attracted to you to be with you barely works.
What's the point of Game then? Nothing in my opinion. Game can make the dating process sexy because it relies on a process of mystery and intrigue. When you Game someone you make them feel wanted one second and ignored the next. You make yourself available and then not. If you look at stories like Twilight or even more mature female based stories its actually a very sexy game to a girl.
Game does NOT actually:
Convince a girl who finds you ugly/repulsive to then find you HOT
Work on any consistent basis
Have any justification given that every man has some girls that are already attracted to them.
This does not mean that a man should not pursue a girl, he still has to make the approach. The thing is girls give out signs all the time. And, unless you're a guy who notices everything, chances are she noticed you before you noticed her anyway.
So, look for signs or just say hi and talk to her a bit and you'll be able to feel if she's feeling you very quickly and if she's not just smile and walk on.
