A recent Penn State University study confirmed that when we smile we not only appear more likeable and courteous, but we’re actually perceived to be more competent.

So now we know that:

• When you smile, you look good and feel good.
• When others see you smile, they smile too.
• When others smile, they look good and feel good, too.

Perhaps this is why Mother Teresa said: “I will never understand all the good that a simple smile can accomplish.”
