You can really want to be the kind of person who gets up and goes to the gym regularly. And you can also simultaneously want to sit motionless on your sofa and passively watch dumb TV programs, even though those things are totally incompatible.
I suspect it may be similar with figuring out whether teenagers really "want" to be mature, responsible, and productive individuals.
I thought it was otherwise: that people who didn't want to work or improve or learn were people that didn't have a good method of doing so, that they were restricted by the system. Long story short, I found out that's radically not the truth. Some people are a little bit icky inside.
That's because you can't start with adolescence. You have to start increasing responsibility from roughly age 2. Get them used to it, reward it, show them the connection between increased responsibility and increased choice and freedom. Then they'll want it. The problem with most adolescents is the 12 years prior.
It's a question of the meaning of "want." I think a small fraction of adolescents can articulate that they "want" meaningful responsibility and structure, or make any efforts to get it.
