Fake It 'til you Make It

"Why should I smile when there is no joy in me? The answer to that is: smiling is a practice. There are over three hundred muscles in your face. When you are angry or fearful, these muscles tense up. The tension in these muscles creates a feeling of hardness. If you know how to breathe in and produce a smile, however, the tension will disappear-- it is what I call 'mouth yoga.' Make smiling an exercise. Just breathe in and smile. The tension will disappear and you will feel much better."  ~Thich Nhat Hanh
