Why do you feel you speak so little? Is it because of insecurities, working alone or simply because you have little to speak about in the situations you are in?

Why do you feel you speak so little? Is it because of insecurities, working alone or simply because you have little to speak about in the situations you are in? Oftentimes people speak for the sake of being heard but don't add anything meaningful to the conversation. Then you get the quiet ones who speak very little but when they do, it is meaningful and everyone hears what they say. I think a lot of us could benefit from learning how to do a little more listening and a little less speaking ;)
