Smiling is legit cool.

Friendliness is cool.
Being courteous is super cool.

You know what could change the world?
Smiling at a stranger you happen to make eye contact with.
Being in a good mood ‘cause you’re just plain grateful.
Being friendly in the checkout line.
A thank-you wave when someone lets you in front of them in traffic. (Honestly, I don’t know how this one is even an option.) 

These seemingly little things do something eternal inside each of us and they start a chain reaction in the people on the receiving end. You will literally be spreading good.

So, go get your smile on. (It’s National Smile Power Day today, did you know?)
And tell me in the comments before you go, what else is COOL to you?!
