If you read the business pages, it’s been almost impossible to ignore the many articles on the topic of “quiet quitting” in recent months. This buzzy term refers to employees—at least half the U.S. workforce, according to polling—resolving to meet only the bare minimum requirements of their job descriptions. When it comes to giving up, however, Annie Duke has something louder in mind. In “Quit: The Power of Knowing When to Walk Away,” the author, consultant and former professional poker player proposes that quitting, the unambiguous kind, ought to be seen as a virtue and honed as a skill integral to both professional and personal success. Instead, it’s often maligned by a culture that valorizes grit and tenacity.
