I have long been in awe of talkative people, I who felt like I never had anything to say. I thought that these people knew a lot of things and I didn't. Recently, I went from having no friends to having many. And I always have something to tell them. I realized that I was in the grip of a myth: that of believing that you had to know a lot of things to talk to people. It's wrong. (Perhaps the opposite is even true!). When you have self-confidence, you ALWAYS find things to say, and things that can be exciting. And it does not depend on your knowledge or your general culture.
