The technique of questioning your thoughts has been popularized by Byron Katie who advocates what she calls the great undoing. Bill just got into the habit of asking himself, is that thought true? And if he wasn't absolutely certain that it was, he'd just let it go. He said, thank you mind for coming up with that thought and move on. That's something that you can begin right now. It will reduce your stress and other people's, but in a way that builds connection and bond ship.
