Don’t shut up–shut down. Let your jaw hang down. Separate your teeth. Take a few seconds throughout the day to relax your face and your mouth. You might be surprised how often you’re clenching your teeth. I’ve discovered that sometimes I tense up and clench doing the most mundane things, like making a pot of coffee. It seems like such a small, insignificant thing, but relaxing one part of your body can really help to, eventually, relax your whole body and mind.
