Thanks for everyone's thoughts so far. Your advice makes good sense to me. Andrew, that sounds like torture, but I will give it a shot.
I am not uncomfortable being the focus of attention if I am talking about something worthwhile. I am also very comfortable just being in the background. The problem arises when I am the center of attention for being annoying or talking too much.
When 3 people call you an ass, buy a saddle.
My goal is to be more present to conversations, listen to other people without just thinking of what I will say next, breathing and responding thoughtfully instead of reacting.
Thanks. And I will look forward to some more advice.
