The most valuable work in today’s knowledge economy is almost invariably work that requires all your mental resources to be focused on one thing — think cognitively demanding tasks like coding, designing, writing, strategizing, and problem-solving. Yet the modern workplace isn’t set up to support that kind of distraction-free “deep work” (a phrase coined by computer science professor Cal Newport). We’re distracted by so many emails, meetings, chat messages and requests for input that we don’t have the time or space to focus on our highest impact tasks.
