Maybe you have the tendency to not let your conversation flow naturally - and I've felt this way. You might not consider yourself a natural conversationalist.

Well this video might be good for you. It's Tyler, known from Real Social Dynamics, and he's explaining (very well) how to naturally be fluent in conversation.

A lot of people, like Tyler mentions he was like before, have trouble coming up with things to say.

Tyler goes about explaining in this video that you don't have to think of awesome things to say, but that it's more about the energy you convery.

Another important idea is that you can develop the trait of being able to converse with women.

I suggest you watch this video if you are wanting to learn how to talk to women or if you stumble with words around girls.
