Turning 30 used to mean hitting your stride as an official adult. But for many of the country?s millennials, it feels like being stuck in perpetual late adolescence. Marriage eludes many. Children? Not anytime soon. Most millennials have some sort of job, but for many a career seems unobtainable. A home of their own? Lots of them have had to move back in with mom and dad or shack up with roommates. That?s not the place where many millennials expected or wanted to be as they enter their thirties. Of course, some millennials have managed to navigate the early years of adulthood just fine. But for many, 30 is looking a lot like 20 used to as the generation that began with so much promise has fallen behind on nearly every adult milestone.
