If women smile at you when being greeted or in Conversation does it mean you are handsomegang??

There's no golden rules anymore. Women sometimes feel obligated to be friendly in interactions with men nowadays. Its woman to woman, and you kinda just have to learn to read people. You have to learn to read people and escalate it accordingly.
I'd say one clear-cut sign, albeit not explicit sign is if women you build a rapport with make a concerted effort to reach out to you. Whenever you talk to women, even women you're interested in, generally don't go in with the mentality I'm going to get her digits right away. If you have a chance to talk to her on multiple occasions; y'all go to the same gym or y'all work together, just be friendly. Women will let their guard down if you don't be on creep mode 24/7.
Women who have no interest will absolutely not reach out to you under any circumstances. That reach out though is completely contingent on you being an interesting and sometimes mysterious person though. This is why people say "focus on yourself and everything else will fall in line"
If y'all have 3 or 4 interactions and she's reciprocating your energy, literally all you have to say is you want to get some coffee, lunch, or a drink some time. And you can go from there. Women know they look good and you're tryna holla. You don't have to be on no upfront goofy shyt like "i like you, let's go on a date" shyt.
There's no easy answer other than trial and error to be honest. And as much as I've learned shyt, it's still a constant battle and learning experience for me. I get women, or used to...in a relationship now...but I was never a dude that got women at will. It was always an effort even if I was never considered #uglygang. Even if hundreds of women made it obvious they wanted me to holler over my life. I'm just not that dude women immediately resonate with. So I had to learn to make shyt work in my favor.
