Our exhausting tendency to grind without relief, hour after hour, day after day, month after month, is more arbitrary than we recognize. It’s true that many of us have bosses or clients making demands, but they don’t always dictate the details of our daily schedules—it’s often our own anxieties that play the role of the fiercest taskmaster. We suffer from overly ambitious timelines and poorly managed workloads due to a fundamental uneasiness with ever stepping back from the numbing exhaustion of jittery busyness.
