I don't have anything interesting to talk about because I live in a medium size town and there is no clubs or anything to do and I am only 19 so I cant go to bars and I also feel like I have short term memory. I only go to school, work, gym and do some hobbies. I think the best tip I ever received about conversation is not to think about what to say because it will help you not filter what to say or something and I think it helps but sometimes its very hard to do. Is there any tips on how to keep conversation going or what to talk about with girls because I feel like with women if its not something interesting then women will not enjoy the conversation and if I feel like the conversation didn't go well then I get pretty upset and I think about what I could of said or done better. I feel like I can talk about a lot of random stuff like video games or stuff I watch on youtube etc but I feel like I need to filter what I say to make it interesting or make it appropriate.

Maybe any good books to read about conversations?
