I think the idea is that adolescent activities prepare us for life as adults, as adults we concern our self with the grown-up version of the same thing. Whether it's running a business or waging war or building machines or whatever. That's predicated on adulthood being a state where you're autonomous and free to do something with your life, and falls apart when we're up to our ears in debt and working as wage-slaves. In the latter scenario, you may satisfy the itch for the thing you've been preparing for by additional preparation. We play video games or watch TV-shows about people going on adventures instead of actually going on adventures ourselves because that's not an option.
