Bill has got a point.
Im working with a wing right now that just got into the game...he only wants to approach the hottest girls around. Problem is, that when he does, he stutters and freezes. I explained to him, we are not trying to pick up, were just working on step one (Open) and he is anticipating the outcome of step 10.
You want to get to know people out there, become more social. Yes, girls have other girlfriends, you will meet sooo many exciting people so don't close that off. Be picky with the one you decide to settle down with, be open minded to everyone that crosses your path. Remember, when you are the cool mofo to be around with, girls and guys will speak highly of you, girls especially.
That in itself will open their friends for you. A girlfriend may introduce you to the girl of your dreams, you don't want to lose that opportunity do you?
