Smiling is a wonderful way of making yourself stand out while helping your body to function better. It can improve your health, your attractiveness and lower your stress level. It does far more than just make you look friendly; it can actually change your life and the lives of those around you.
So, the next time you're feeling down, try a smile!
Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy. -Thich Nhat Hanh
