Anne Helen Petersen investigates why millennials became the 'burnout generation,' examining the structural conditions that transformed exhaustion from an occasional state into a permanent way of being. Drawing on her viral BuzzFeed essay and extensive additional research, Petersen traces how this generation was raised to optimize every moment for future success, internalized the message that passion should drive career choices, and entered adulthood during economic crises that made promised rewards perpetually out of reach. She examines how helicopter parenting, the collapse of stable employment, student debt, and social media's constant performance demands created workers who cannot stop working yet never feel they've done enough. Petersen, a former academic turned journalist, brings both scholarly rigor and personal vulnerability to her analysis, sharing her own struggles with tasks that should be simple—scheduling appointments, answering emails, maintaining friendships. The book explores how burnout manifests differently across class, race, and gender lines, with women and people of color bearing additional burdens of emotional labor and code-switching. Petersen challenges readers to recognize burnout not as individual failure but as a systemic problem requiring collective solutions: stronger labor protections, universal healthcare, affordable housing, and cultural shifts away from defining human worth through productivity. This diagnosis of millennial malaise offers both validation and a framework for understanding why self-care solutions feel inadequate.
