From the Smile and Move Website:
Be careful to keep your personal challenges to yourself and those closest to you.

The people around you have challenges of their own and likely won't be able to give yours real attention. Also, in time (if we're awake), we begin to see what a complete waste of energy a complaint (or whine) is even to the people who might be most interested... ourselves.

Once we embrace this fact, complaining less should be fairly easy... until someone around us begins. At that point, we might have a tendency to join in. When we smile, we remember to do what we can to minimize this tendency. When we move, we express care for another's situation and help if we can.

Strive to be complainless.
