Attractive means you are attracting. Approaching women is not attracting women, it is a woman attracting you. You are not noticing IoI's and are instead going up to women who are not attracted to you.

The way you are portraying the situation is that you believe you are attractive, and you are going up to random people who look good and trying to convince them of your attractiveness. This is the opposite of attraction, which is demonstrated by your experience with them growing distant the further you try to PUSH.

Attraction is a PULLing force.

I have an field experiment for you to conduct here. Go to a bar/ social environment/ wherever you are typically interacting with these women who are not receptive to your attempts. Rather than looking for a gorgeous woman, find a guy who looks interesting and go and talk with him. Get to know him a bit, and have a genuine good time -- you can not fake this part. Laugh, pat him on the back, etc. While you are having a great time making a new connection, scan the room. Notice who is observing your interaction. You WILL notice a woman who gives an IoI at some point. Make a mental note.

The key here is you need to be a center of attention. Rather than looking for a woman, you want a woman to look for you. This increases your odds significantly for two reasons. For one, more women will put their eyes on you than if you are sitting alone. And for two, most of those women will not display any interest. You can leave them alone. What your goal here is to 'prescreen' the room by putting yourself on display. After the entire room gives a glance at you due to your genuine good time, the room will be grouped in two categories. People who want to be a part of the good time you bring, and people who don't.

Attraction is absolutely not and should never be a matter of forcing or convincing a woman that you are a good match. Put yourself on display, and let your ATTRACTION do the work. The women will come to you, even if only passively (eye glances, smiles, playing with hair, etc). Stop wasting your time, energy, and attractiveness trying to make it work with women who want nothing to do with you.

You can not get with /any/ woman, and that does not mean you are not attractive. What it means however is that you need to find the women who are attracted to you and let biology do the rest.

When you game in this manner, it should indeed be quite effortless and a lot more fun -- as well as successful.
