A Kind Word and a Smile (Reprinted from my RevolutionSolution blog)
Sometimes becoming part of the solution to the world's ills is to share a smile and a kind word. It doesn't always involve picking up litter or changing someone's tire or giving them a jump when they have a dead battery. Sometimes all you need to do to make the world a better place is to smile at a stranger or wave as you pass someone on the street. I've moved to new places and simply started waving campaigns, being sure to wave at my new neighbors when I pass them whether I know them by name or not. I just assume that I have moved to a friendly neighborhood. I make sure that I slow down and move over if they're out there walking or running or biking. I especially slow down if they're out there walking Fido, since you don't always know what Fido's going to do even when he's on a leash. Even if the place you live isn't particularly friendly when you arrive, just start your own waving campaign. Friendliness is one of those things that tends to be contagious. Try it in your neighborhood. It might take some time before it catches on, but you'll be surprised how quickly it spreads with little effort.
