When you lock eye contact with a woman, do not smile or say "Hi" until she does. If she smiles, you smile. If she says "Hi," you say "Hi." Do not say "Hello." If you smile or say "Hi" first, you may lose her.
SHOCK and AWE is not high risk. It sounds like it is, but it's really not - and I'll explain why in a moment.
It's not even advanced. I'd call it intermediate. If you can open, and you can get attraction, and you can chill out and chat with a chick and not get weird - you can do this.

The only time you do not look a woman in the eyes is when you are "motioning away" as you mention something "bad", such as her borefriend. Anything "bad" is associated with "looking away."
As you're doing so, say "hi" and give a smile to every woman who passes you by, and who is next to you, and who is in front of you, or whatever. The smile doesn't have to be this big cheesy grin, but whatever is your normal, comfortable way of smiling. {Any kind of smile shows you're not depressed, nor someone to be afraid of.}
Tomorrow, or Saturday, or Sunday, groom and dress yourself real nice. I'm not asking anyone to put on any suits, or ties, or jackets (unless that is your comfortable style), but rather dress in your own comfortable, natural way, wearing clean and at least reasonably pressed clothes. Then drive to the nearest shopping mall/center and walk around looking and damn near everything.
