Yes, I have learned to some extent to do what you are describing. It doesn’t work perfectly and you have to work at it pretty persistently. We’re sick of people saying “just relax!” but they’re not entirely wrong. The problem is the word “just.” Relaxing does help, but it’s not at all easy. It takes a tremendous amount of mindfulness to train yourself to *actually* relax your body when you’re in a scary speaking situation.
