How do you start a conversation?

I want to meet new people and talk to them on discords and etc, but I just don't know how and where to start (x_x)⌒☆ I had already joined a bunch of servers, but I don't interact with any of it. I'm not used to hold conversations with a large group of people because I'm shy (⁄ ⁄•⁄×⁄•⁄ ⁄). I hope you can maybe give me some tips and advice ｡ﾟ(TヮT)ﾟ｡
