It’s just another day at school. Another day of avoiding awkward glances while you walk to your next class. You pass by your friends and some people you’ve never talked to before.

Suddenly, you see someone you hardly know, give you a big, toothy smile. There! Your day is made just by this one fleeting gesture.

Just the simple gesture of a smile can make all the difference in our days. Smiling is proven to reduce stress and increase productivity. It can also improve our mood and is 100% contagious. Chances are that if you smile at someone, they’ll want to smile back.

So go on. Give someone a big ol’ smile, and make their day.
