The next time you realize that your hands are clenched together, ask yourself what is it that you're feeling. We naturally clench our hands when we have feelings of nervousness, anxiousness or uncertainty
If you ever notice your hands clenched, take a moment and allow them to release and at the same time take a deep breath and feel your entire physiology shift. Let go of some major tension. Maybe that tension is serving you for a moment, however your opening back up can bring a smile to your face and allow you to possibly not react to the situation next. How you react to your environment is going to be how you experience it.
