Gentlemen, this is the answer to much of what is missing from peoples game. Maybe yours.
Ok, I have given the same piece of advice on various forums about 6 times today so I feel it's time to address and discuss this.
I have noticed a trend for guys in the community to worry about what the other guy is doing. "This guy talks to my girl" "I got back from the toilet and a guy was talking to her" etc etc etc
Now I am a firm believer in being aware of your surroundings but keep your eye on the prize. When an AMOG enters the set don't be afraid to let him run game on your target confident in the knowledge she is already yours and your unaffected state/flippancy will cause her to qualify further, plus open lots of Us vs Them doors for you.
Also in a more long term situation, I hear "this guy is talking to her" and stuff again you have the girl be confident in your abilities to keep her. Start changing how you act and you WILL lose her.
Another one that crops up is she has/is having sex with other guys etc etc lots of guys don't like it and here is why I think this is.... confidence.
Confidence, is not something which I think can be taught it comes through repetition. You become confident in your ability because you assess it against criteria. I personally am a good cook, not great but confident I am better than most people my age. I know this because I have tried their cooking and simply mine was better. So begin looking for these affirmations in your romantic life ( I am a better kisser because this girl said, I have a great ass this girl said etc).
This confidence in my opinion helps you to concentrate on what you are doing safe in the knowledge the other guys don't matter. (I had more to say but am a little tipsy so will add it later).
Anyways time for an awesome ending line, Pickup is a one horse race worry about the others horses and you will fall.
Ps who cares how close they get to getting her winning is winning
