Four years ago today, two bombs detonated at the Boston Marathon killing three and injuring more than 130. In the worst of situations, often we see the best in people. As innocent people were injured in the blast, others ran to their aid. Complete strangers helping strangers. Using their own shirts as tourniquets, carrying the wounded to safety, and numerous other acts that truly represent what the human spirit is all about.

Mankind is inherently good. You see it in tragedies like the Boston Marathon, 9/11, Sandy Hook, and even at a car accident on the highway. The first people to render aid are complete strangers that stop to check on the people involved, just because it’s the right thing to do. Just because deep down, we know we’re all in this together.

It shouldn’t only be prevalent in times of major crisis though. This is something that we can, and should, practice every day. Something as simple as a kind word can absolutely change someone’s life. As silly as it sounds, it’s true. The power of a smile and genuine compliment that just lets a person know that they’re important and someone really does care that they’re doing well is one of the most powerful gifts you can give another person.

Think about the last time someone paid you a genuine compliment out of the blue. How did you feel? What impact did that have on your day? When is the last time you did that for someone else?

I challenge you to do that today. The next person you talk to, before you say anything to them, smile and think of something nice. Start the conversation off with a compliment. Take time to show someone else how important they are. Do this enough, and it’ll start happening to you too.
