High standards, attention to detail, and self-control are invaluable qualities at work. They’re also aspects of perfectionism, something to which many high achievers credit much of their success. But Ellen Hendriksen, clinical psychologist at Boston University's Center for Anxiety and Related Disorders, says being your own worst critic can also lead to constant dissatisfaction at work and alienation from coworkers. Her new book is How to Be Enough: Self-Acceptance for Self-Critics and Perfectionists. Drawing on her own research, clinical work, and personal experience as a perfectionist, she explains where perfectionism comes from and how it affects teams. Hendriksen shares how not to be so hard on yourself—while still keeping your high standards.
