TACKLING TEENAGERS: Your one weapon - and it must be used judiciously - is embarrassment. Threaten to use it in front of their friends.
Utter nonsense. You also have removal of their computer privileges, confiscation of car keys, bad reports to their grandparents (who then don't send money), PT, and the dreaded, "We will all sit here and I will read aloud from (whatever I'm currently reading) until you are ready to comply."
There is embarassment, of course, too. "I will go to your next Scoutmaster's Conference and tell your leaders that you are violating the Scout Law in these ways. I will recommend that you not be granted your next rank, because you are being a scandal to the BSA."
So the authors aren't too bright, and whatever they say about holding doors has a good chance of being as erronous as their teen-training advice.

*Wp-krack!*
Jump! Jump through the flaming hoop! Jump!
... yeah, sometimes I’m random.
