Think of all the people you’ve brushed up against as you went about your day today. Were their lives made better by the encounter? Even something as simple as a greeting or smile can brighten someone else’s day, and they in turn will be more encouraged to brighten someone else’s day and so on and so on and so on.  Good cheer ripples out into the world endlessly. So, of course, does a dour grumpy mood. But who needs more of that?

Consider your actions today. You’re making ripples of one kind or another.
