卡爾．紐波特《沒有Email的世界: 過度溝通時代的深度工作法》 From New York Times bestselling author Cal Newport comes a bold vision for liberating workers from the tyranny of the inbox--and unleashing a new era of productivity. Modern knowledge workers communicate constantly. Their days are defined by a relentless barrage of incoming messages and back-and-forth digital conversations--a state of constant, anxious chatter in which nobody can disconnect, and so nobody has the cognitive bandwidth to perform substantive work. There was a time when tools like email felt cutting edge, but a thorough review of current evidence reveals that the "hyperactive hive mind" workflow they helped create has become a productivity disaster, reducing profitability and perhaps even slowing overall economic growth. Equally worrisome, it makes us miserable. Humans are simply not wired for constant digital communication.
