I've started working on myself and I'm doing pretty well at the gym but my biggest detractor is the lack of ability to hold a conversation. I've just spent too much of my life nerding out over math and hobbies that don't have many women like homebrewing. I try going out and when I approach the conversation fizzles out quickly and I can't think of much to say since I am pretty boring to most people. Any ideas on where to get material to talk about with women or how to get her to talk about something I can at least relate to and add to the conversation somehow?
