If you are reading this, no matter where you are or what you are doing, at your very next free moment:
Do something nice for someone.
Email a friend to tell them how much they mean to you, send you mom an e-card, do some of your roommates dishes, offer to bring your cubical mate coffee from the break room, tell a coworker how much you enjoy working with them, pay someone elses toll on your commute home (but please don't tell me you're reading this DURING your commute ;-). It doesn't matter what you do, it doesn't matter how big or small, just do something nice.
You don't have to tag anyone, you don't have to repost this unless you want to, but if you can take one moment out of your day, and make the world a friendlier place.
