If you like to blab on and on, restrict yourself a bit. It's better to listen then to be all excited and spill your life's story to girls you just met. Stay a bit mysterious but not annoyingly concealed. Listen to what is being said but stay in control of the conversation by asking questions and stuff like that. Take the time when you are listening to think of a good subject to talk or ask questions about - or a witty response to what is being said. Make sure the topic isn't stupid or boring, talk in the others interest. Before you say something or start on a topic, imagine what you are going to be talking about would be recorded and shown on tv or something like that...is it REALLY worth talking about and cool? or is it boring, pointless and embarrassing. Speak quite slow and with emphasis like its very important.
Pull this all off with minimal pause, don't sit there thinking for 5 seconds between exchanges or questions.. it needs to be bang on right away, and this comes with practice . Good luck playas, get your dates and lays.
