The 3 most common problems guys I meet have are as follows:
1. They won't approach hot women because they believe they must already be taken. I don't need to go into this for your question but I can do if anyone asks. The bottom line is, just fucking do it.
2. They don't know what to talk about to get a woman interested in them. Clearly, this isn't you, but I'll get to your problem in a sec. I should point out, most of what we convey to others about ourselves is through our body language, eye contact and how we touch. If you can hold a conversation then you're fine as long as your body language is relaxed and your hands are animated, allowing for natural touching. The fact that you can hold a conversation and are socially adept enough to be so relaxed and comfortable with her straight away will make her feel equally comfortable and she will be open to getting to know you more.
Your problem is that you don't know how to start this chain of events, and that's a shame. You feel like you have all this power and you don't know how to use it. No biggie though - all you have to do is say hi. That's right, saying hi and asking how she's doing, the same thing you do when you see someone you know in the street, works on complete strangers aswell. You seem confident in your conversation skills so you could continue from this very easily, correct me if I'm wrong. If you feel the need to justify why you approached her, tell her she looked interesting and you wanted to find out what she was like. Women appreciate this kind of honesty, and your approach is the closest they'll come to being swept off their feet. Consider this for a second - they're used to being hit on by guys in bars who have no confidence when they're sober. Guys rarely approach them during the day and when they do, they're afraid to get to the point! So, even if she likes the guy, nothing comes of it. You will be told that they get hit on a lot during the day, but this is mere speculation... they get whistled at from across the street and guys pass remarks as they walk past, but that hardly constitutes as anything of worth. If we're talking actual approaches where guys are up front and tell her they are interested in her, it happens extremely rarely.
3. They can approach women and have conversation, but are afraid to ask for their number or tell them they're interested in dating them (the whole reason they approached in the first place). It's not exactly fear, a lot of guys just don't know how. I have a feeling you might get this. Again, no biggie. After you've been talking for a while, check your watch, and continue a little before telling her you were on your way somewhere and need to get going, but you'd like to continue this later. Now you can get her number and arrange to call her. It's important to do this while you're having a good interaction; if you hit a dead spot in the conversation and spring this on her, it looks like you wanna get the fuck outta there cos you can't think of anything else to say.
Any questions?
