Hi, I'm almost 20, male with zero experience with girls. I recently notice a pattern in my life: most of my interests are quite geeky (I was a lot into anime, videogames, sci fi and chess) and don't really require social interaction (even those that might be more social like learning languages were done mostly from home, without need to interact). Actually, most of my social interaction are at university and with my friends from high school and I struggle interacting with people I don't know, especially girls.

Before starting going out with my current friends my social life was really poor and I didn't have a basic understanding of social interactions. Now it's better because I'm not completely clueless but I still struggle really with people I don't know. Sometimes one problem is the fact I can't really relate with them because I didn't experience the same things as many other guys/girls my age and my interests are many times pretty niche. Also I never really partied a lot. I'm more the kind of guy you could find in a library or at the margin of a social interaction.

I want to change this, I want to become smoother in social interactions and build the kind of lifestyle that naturaùlly draws girls in and I want to start with my hobbies and interest. What are some hobbies that can make me better in interacting with others(especially girls my age) and give me more chances to meet new girls without resorting to cold approach? Which make me a more well-rounded and interesting person?

I want to bring change into my life so I can become more confident and become someone who can have some chance with girls, focusing a lot on inner game rather than try to cover my shyness and low self confidence with faked confidence and game/routines. I tried it without fixing my life beforehand but I couldn't get over my shyness and suffered from a backlash and now I'm still unable to get anywhere with girls

I would also like to hear if there's anyone coming from a similar situation who was able to fix it
