If, for example, one wanted one's teenage son to mop the floor where the messy dog had slopped water...
Or if, perhaps, one wanted one's teenage son to finally empty the dishwasher...
Or if, perchance, one wished one's teenaged son to begin doing the online assignment one had been nagging urging one's son to complete for several days...
One might consider trying a carrot and stick approach...
(Just as a completely random example...having a friend over to go fishing)
Bribery.
There is no substitute.
