I like this, that BadKnee said:
"Everyone you meet, (man or woman), smile, connect, find something to "love" about them. Really "see" them - who they are, what matters to them. Everyone has something about them. Once you see something in others, something to love, they will reciprocate and see something in you."
I work in diplomacy. It is my actual job to make a connection with everyone I meet, even if they don't want to like me or work with me. And yeah, it's not about making yourself something specific and desirable, it's about finding the clue in the other person. When I meet someone I make wide ranging small talk initially, with open ended questions, revealing a little about myself (and they tend to respond on a reciprocal basis, culture dependent). What I'm looking for is the little gift tag sticking out of one part of their persona, and when my questions mean I get that little tag, I pull it and pull it, to find out what makes them tick. That's my clue, that's my way in. I am looking for something we have in common, something about which we can connect. I have never yet found someone with whom I couldn't connect on some level. This is how to network for maximum effect - it's not quantity, quality.
And once you've found that way in, they're looking at you as a real person, and you're seeing them as a real person. I am not pretty at all, and I've actually got quite a difficult personality, but I connect with a lot of people and I'm apparently rather successful at my role.
I am sure this technique could be used to make connections with people you meet socially or through work, and could lead the way to a potential romance.
P.S This makes me sound like a fake calculating person. I'm not. I genuinely love meeting people and finding out about them. And I think they realise that.
