You know what the world needs? Kindness.

As many commenters noted last week, making a difference and giving back to the world doesn’t always require large gestures. Small kindnesses can go a long way.

This week, let’s give a little bit to as many people as we can.

Smile.

Smile at the person you pass on the sidewalk. Smile at the cashier in the grocery store. Smile at the mom struggling with crying toddlers in the mall. Smile and wave at the dude who cuts you off in traffic – the one who may be coming home from getting really bad news or on his way to meet with a lawyer.

Let’s all smile at strangers this week.
