Small things like this might just have a bigger impact than you can imagine. In his bestselling book The Tipping Point, author Malcolm Gladwell notes that social changes often take place with surprising ferocity, when an invisible but crucial point is reached that destabilizes the current paradigm. Everyone takes the status quo for granted… right up until the moment that a critical mass of people (nowhere near a majority, just a sizeable percentage) shift their behavior. Then a tipping point is reached and everything changes.
