I guess instead of forcing people to change we need to try to show people why change can be good, na.
Hey now... non of this foreign mumbo jumbo tactics. That just won't stand, in the States...
I think a better approach would be to show what it's costing the individual... Unfortunately, I don't think it's enough yet. Kinda like when a daycare charges a $5 fee when parents pick up their kids late -- it causes more parents to come late as $5 isn't enough to warrant a habit/lifestyle change. Corollary with, "my car is good enough on gas."
Time is the best teacher. Unfortunately it kills all its students.
