"I'm of the view that people need to be fully engaged in adult life in their mid-twenties," says Dr. Brad Wilcox, director of the National Marriage Project at the University of Virginia, as well as associate professor of sociology at the university. "People flourish in their careers and their lives in general if they get serious during this time of their life. If they are still jumping from one job to another, they are not getting those networking experiences that will serve them in their career."
