So I checked your posting history. You frequent /r/askreddit for sundry topics, but your posts on PCs, mechanical keyboards, gaming, minecraft, and science paint a clearer picture. I'm going to go out on a limb and say that you have a rich inner world BUT, when you leave the comfort of the glowing blue screen, you suffer from analysis paralysis. You freeze up instead of using default choices. So here's a default choice for you: people want to have conversations with people they perceive as having value.
I've highlighted the two most important parts of this sentence, because they're the parts people fuck up the most. First off, perception. If you have a rich inner world BUT you don't sell yourself, they're not going to know! I know h2h combat, nanotechnology, economics, and the Japanese-US import markets! But unless I put myself out there, people won't know to ask me about them. Either namedrop, wear stuff, or even have a phone wallpaper that speaks for you.
But what kind of wallpaper? What kind of names to drop? That gets into Value. You seem like a smart and clever guy. I would say I'm the same. For me, I froze up when I worried about talking too zealously about my interests and boring the crap out of them (seriously, nanotechnology? That's a tough sell compared to titties). I also worried about offending someone; I can't tell you how many times I've talked to a steak-and-potatoes person to expand their palate to delicious Vietnamese food, and not-so-subtly implying that they're as childish as a kid who pushes his peas off the plate and into Fido's mouth.
But you know what? You shouldn't be afraid to make mistakes. Whenever you step over the bounds, just apologize and ask about THEM. Since you/I talked about nanotechnology, is there something they're crazy about? Or maybe there's a weird food THEY like, but which others might not appreciate at much?
People love to talk about themselves. And if you keep an open mind, you can hitchhike off of them.
