I think it comes with age and experience. When I was right off school, I had the same problems as you guys, mainly overthinking about everything, and everybody you meet, makes it hard to just have casual conversations. Just as I learned in soccer, you should just stop overthinking and overanalyzing, and just go with it, causually and naturally. Also, in my current job, I interact with a lot more people everyday, so I was forced out of my shell a while ago. But, when you are in parties, you have to make some effort to reach to people and talk to them. Even thou nothing might come out of it, it is better than just staying in one corner and doing nothing. Anyway, stop reading books and just put yourself out there and practice. It will help when you meet girls.
