One of the biggest ways I see is the idea of when to move out of your parents' household.

At least in American society, it's considered imperative to move out ASAP - when leaving for college, or at the latest, upon graduating. Even if it means dumping a huge portion of your paycheck into rent for place barely 15 minutes from your parents' home.

In other societies it's more common to live with your parents well into adulthood. Marriage is often the point where you have to move out.
