Most people drastically underestimate the influence of a smile. Not only does a simple smile have a significant impact on the person receiving it, but there is an actual physiological benefit for the person doing it.
You never know how much your smile can mean to someone you love, or even to a perfect stranger. It may be the only one they get that day.
It’s better to be the one who smiled than the one who didn’t smile back. 🙂
A Smile is the Prettiest Thing You Can Wear
If you only have one smile in you, give it to the people you love. Don’t be surly at home, then go out in the street and start grinning Good morning at total strangers. – Maya Angelou
