Thich Nhat Hanh recommends we try a Smiling Meditation. Smile whenever you can, Smile while you are driving, standing in line, at the gym, at work, or anywhere you are. You will feel better and your mood will change. People around you will respond to you with increased kindness. It's contagious! Even if you only see a picture of someone smiling you naturally feel happier. So smile...even if you have to fake it you will see the effects and the benefits will be the same!
