The best thing about kindness? It's free. It's infinite. And it multiplies.
One small act—a smile, a compliment, a moment of patience—can ripple outward in ways you'll never know.
That person you smiled at? They might have been having the worst day. And you just made it better. And because you made it better, they'll be nicer to the next person. And that person will be nicer to someone else.
