Amy Wrzesniewski, a professor of organizational behavior at Yale University, has made a career studying how people think about their work. Her breakthrough paper, published in the Journal of Research in Personality while she was still a graduate student, explores the distinction between a job, a career, and a calling7. A job, in Wrzesniewski’s formulation, is a way to pay the bills, a career is a path toward increasingly better work, and a calling is work that’s an important part of your life and a vital part of your identity.
