How to unlock the simplest most influential weapon that we have on our faces? We give ourselves a quick look in the mirror every single morning before leaving the house, just to make sure that we look good. But sometimes we still show up at the office, get the kids from school, or return home to our spouses with a frown on our face.  

Why do we pay more attention to what we wear on our bodies than what we wear on our faces. Smiling, as simple as the act is, is so incredibly powerful, and of course it can't be an insincere grin, we all know what that looks like and we can all recognize that a mile away.  

But a real smile can turn someone's day around, it sends a message of goodwill, it says to someone who is under a lot of pressure from their boss, their customers, teachers, parents, children, whatever it is, that all is not hopeless.  

People who smile more tend to manage, teach and sell more effectively, they live happier lives. There's far more information in a smile than a frown, that's why encouragement is a much more effective teaching device than punishment, even when we're talking on the phone, a smile comes through in our voices.
