It's not difficult for most people, and takes a few moments of time to begin to enjoy those benefits. during the next minute you can begin to free yourself of tension.
Clench your teeth...hard!
Relax them.
Clench again..hard!!! 
Relax.
Decide you prefer relaxed to clenched. Let that relaxation flow to your cheeks and jaw. Now, keep it that way.
Check yourself now and then during the day and if your teeth feel clenched or achy, undo the stress that has built up. You alone can do this. You alone can choose to be filled with tension...or not!

YOU are in control of your own thoughts and mind and can choose the direction of your thoughts.
Please choose life-affirming, healthy thoughts that lead to your well-being in all aspects of your life.
