Eh, at least you can come up with SOMETHING as an answer, that's a huge start in and of itself.
That being said, now you have to change your focus. This is a conscious decision, not just something that happens. This is something you do BEFOREHAND and then when you get into a situation where you are around girls, you recall it and use it to propel you forward.
What I mean by that is that you need to start with two things:
1. Change the way you view YOURSELF. This means that instead of thinking of the girl as the "prize", you think of yourself as the prize. How do you do this? Well, you start with baby steps again. How many times do you see a hot girl and think to yourself "Damn! I'd tap that" or "God she's SOOOOO hot!"??? Well STOP THINKING THAT! You have to consciously be aware that you are doing that. Instead, start thinking "Damn, wouldn't she like to f**k me?" or "She thinks I'm hot". Trust me, I had to do this and it worked for me (partially). Next thing you have to do is work on the way you present yourself to them. Take conscious notice of how you work your body. I mean, don't let your head go down, keep it up. Keep your shoulders back. Stand up straight and walk with confidence. Next, initiate eye contact. It's just eye contact, nothing more at this stage. Every girl you see you SEARCH for her eyes and hold eye contact with them as long as you can. Eventually you'll get to where you can keep the contact until SHE turns away. When you get to that point, you're ready for the next baby step. GREET HER. Nothing major, just a "How are you doing?" as you walk past. You're not approaching here, you're not asking her out. You are just asking how she's doing, and letting her answer and keep walking. Trust me, these little things make a HUGE difference when you get to the final stage. Continuing the conversation and approaching. You have to get the inside worked out first, then move to the outside.
2. Change how you view HER. She's not some goddess. In fact, most of the hotter girls have the WORST personalities because they never have to develop it. They just sit back and let people approach them and their life pretty much propels itself because they look good. So, knock her off her f**king pedastool! She eats, ****s, farts, burps, pees, and pukes just like you. She has needs and insecurities just like you. In fact, she's probably more insecure than you are! Keep this stuff in mind. She doesn't deserve special treatment because she's pretty. To hell with that!
Keep that focus in your mind at all times and move slow. You don't have to change overnight. Just change your focus from pleasing HER, to her pleasing YOU.
