It's good to know I'm not alone. Mine isn't that intense; I only do this several times a day, but when driving or in the shower, I am frequently giving speeches in front of thousands, or debating publicly on live television. I constantly call myself out on aspects where I'm weak, and correct myself. I don't schedule time or do this deliberately; it kind of just happens. But what I've found is that is has helped me so much in my face-to-face communication at work.
