Scott Newberg flew into Logan airport in the middle of the night. He went straight home to his office, and in the dark room the blue light of his computer glared — a screen full of unfinished work that piled up while he was gone. He sat down at the keyboard, and that's when he had the revelation. He gave notice. He has no other job lined up. He has no real plan for how he will make money. But the career he had was not fulfilling.

One of the contributions Generations X and Y have made to the workplace is the quarterlife crisis. It's not the midlife crisis, typified by a baby boomer in a Porsche obsessively speeding. The quarterlife crisis happens in one's twenties and more likely involves takeout pizza and obsessive IMing.

The journey toward crisis begins at college graduation, when the typical student has about ten thousand dollars in loans and no skills to land a decent job. Frank Furstenberg, professor of sociology at University of Pennsylvania, says the transition to adulthood is “more arduous today than it was fifty years ago.” Employers are not hiring people in their early 20s for staff jobs. “Employers hire temps for positions that don't require experience. Society can incorporate people only when they get some experience working and there is a better match between employee and employer.”

With little to lose, most twentysomethings use their post-college time as an opportunity for finding oneself, seeing what's available, and trying a lot on for size. (Which translates to more than eight jobs before turning 32.) The new behavior, which looks remarkably like flailing, is appropriate for the new workplace. Jeffrey Arnett, psychologist at Clark University and author of Emerging Adulthood says, “People have different personal time tables and it's nice that people can make choices that are right for them.”

Yet this new phase in one's career is unnerving in light of the stability of previous generations of people in their 20s. And if the job-hopping doesn't stop by age thirty, the stress intensifies to crisis.

Emerging adults “have high expectations for work. It is not just a way to make a living,” says Arnett. They want work to be fulfilling and to be an expression of their identities.”

This is true for Alexandra Robbins. She took the first job offered to her after college because she was “seduced by the trappings: Short commute, friends at the company, office with a door. The pay was fine, but the work was not rewarding.”

She realized that in the post-college world, people are judged by their answer to the question, “So, what do you do?” And she knew she needed to do something that could define her.

Typical of her generation, she does not claim to have extravagant dreams: “I never had a big dream. I wanted to make a living writing. Dreams that are too specific lead to missed opportunities.” As a writer she has become a sort of spokesperson for the generation of lost college graduates. Her recent book, Conquering Your Quarterlife Crisis, chronicles the ups and downs of people like her, who finally found their way.

Like Furstenberg, Robbins sees that previous generations were more equipped to make the transition to adulthood. “We cannot gain a foothold in society until age thirty. But our parents' generation has twenty in their head. The crisis is a clash of generations.” Fifty years ago, people expected to find a job for life right after college and be married with kids by 24. But for the current generation, Robbins declares, “Thirty is the new twenty.”

Sure, GenXers and Ys have high expectations for work, and maybe they're unreasonable, “but the only way to find out is to try,” says Arnett. “Most people will fail. But by the time people are in their late twenties most have made peace with their dreams. Psychologically people tend to accommodate themselves to whatever they have.”

The problems start around age 27 or 28, when most people find a career. For people who do not feel settled, there is panic and what Arnett calls “desperate and dangerous” measures in order to reach their goals.

Which brings us back to Newberg, whose wife is about to give birth. His plan is to stay home with the baby while she supports the family. And he will write music for commercials, though he has scant experience in the trade. And he will “write some novels and shop them around.” He wants to support his family in five years but has not figured out how many novels or musical compositions he would need to sell to do that. Those people who are not turning thirty might bristle at Newberg's plan. But he says, speaking for many in his generation, “I don't want to be eighty and regret not taking this risk.”
