Have you ever noticed how contagious a smile is? Someone smiles at you at the grocery store...a perfect stranger...and all of a sudden your immediate reflex is to smile back. Years ago, I had a client who said that he "practiced" smiling to help improve his mood. I thought this was kind of crazy until I tried it out myself. It really does give your mood a boost. I dare you to practice smiling and see how it boosts your mood. Watch how it affects other people. Go ahead, smile!
