I think you just need to focus on how to talk to girls in a friendly way for now. Other guys get the girls because they talk. They aren't smarter or more thoughtful than you, at least not all of them. The other day I sat with a "friend" of mine in a bar, both of us hold advanced degree in science, but we are both shy. So, we spent the night talking to each other about science, while other guys were talking to girls and laughing with them, probably about silly things. You see. It's an unfair game, you might say, but it's the way it is.
