Women love to be met, but tend to neglect their responsibility to be ready. This comes from years of misguided advice from media and mentors who didn't have any more a clue than they did about how to attract the right guy. Being ready is to be approachable, not 'appealing'.
I believe it starts at the first impression. For whatever reason, it seems like women want men to surprise them with their introduction, and call it being "original". If this was a talent show, fine, but in real life a bland "Hi, how are you?" may be as genuine as it gets. Women have to stop expecting men to jump through flaming hoops reciting Shakespeare. I can see how it's convenient for women to sit back and say, "Show me what you got", but keep in mind there's very creative assholes out there. Don't make the first cuts based on the 'hello' unless it's just way left field(i.e. "Ay yo bitch" is unnacceptable). Pick up on more subtle signs that are less voluntary. For instance, where does his eyes focus in the first 2 minutes of conversation? Being up close gives us a very tempting opportunity to see better what we couldn't from a far especially when we have a hidden agenda. Knowing what too look for speaks to your priorities and therefore what kind of men are making it through your filter. Also, be careful of the subtle signals you send as well. A man with genuine intentions will do everything but run the other way when an attractive woman rolls her eyes unwelcoming his presence.
This brings me to my next point; The difference between Mr. Right approaching you and keeping his distance could also be your demeanor. Shake the whole "bad bitch" ora that you put on to prove how self-assured you are in public. You know the type; the road is her runway, nothing's cool enough for her attention, if it rained she'd drown for her nose being so high, etc. While nothing's wrong with looking and feeling great, men tend to feel more comfortable approaching women whos' heads are still on their shoulders. I've even found that some women get approached more when in their comfortable wear which could very well speak to that point. It doesn't mean he's not "man enough", but rather he doesn't need any more stress in his life. Long story short, confident not cocky is ALWAYS the way to go.
At the end of the day, it all comes down to the kind of guy you're in to. You'll always be approachable to somebody, but who do you want that to be? Hint: Mr. Right
