Here in the U.S., we don't do a whole lot of positive encouragement of anything. It seems that most of the time, we prefer to make what we don't want people to do sound bad, scary, dangerous, etc rather than trying to make whatever we want people to do sound really attractive.
This gets really wearing on me, personally, as I'm of the temperament that I don't enjoy living in fear of things, I don't enjoy tearing other people down, and I don't enjoy the feeling of danger and oppression that all the negative advertisement throws over things.
I would much rather encourage positively. Anyone else join me?
