The world feels bigger as young adults move around and encounter what are called “large world problems,” or those for which there are no right answers. There is no way to be sure about where to live, what to do for work, or when, whether, how, or with whom to partner. What’s worse is that the underlying existential questions—“Will I be successful? Will I be alone? Will I be loved? Will I be happy? Will my life have meaning? Will things work out for me?”—may go unanswered for a decade or more.
