Probably best to be a man of few words. Its all about body language. Make people impress you. What's there really to talk about these days anyway.
These kinda threads usually strike me as pretend. What do u do where u have to talk so much?
Probably just get wasted or listen to music etc with buddies right? Lol.
Women is who u nees to talk a lot with.
You may want to talk more, but you already listen. Something way more important than talking. Communication is talking, listening, and having something worth sharing. You may not say anything at all but still be communicating better than most.
I hopefully understand your frustration and wish you the best of luck. I think what helped me communicate the most was opening up about what I was feeling without having it turned into a joke of some kind. You might talk more than you realize, or you may not really be missing out on as much as you believe.
Pay attention to any feeling you may have when trying to talk: tight stomach, sweaty palms. That might be an indication you feel threatened or intimidated when speaking. If you feel dizzy, short of breathe, you might be hesitating too much. Whatever it is, just blurting out whatever pops into your head might be a good place to start. Then think about what you said afterwards.
I think simply telling yourself you are going to be more sociable would do it. Visualize the goal and see yourself acheiving that goal. No different from any other kind of self encouragement. Don't expect to be able to sort out any reason, it probably does not really matter why this is happening. Talking is something people are capable of doing. Like I said, you might also just have unreasonable expectation and believe that you have a problem when you really don't. Any of this kind of thinking would help you to convince yourself to at least stop worrying about it.
