When your phone buzzes or a notification pops up your screen, do you stop what you're doing to look and respond? That's what many of us are doing. Even though we think we should be less distracted by technology, we haven't admitted the true cost of these interruptions. This week on Hidden Brain, we talk with the computer scientist Cal Newport about how to cultivate our attention, and what we gain by immersing ourselves in meaningful work. It's part of our series You 2.0, in which we'll explore how we can all make better decisions and cope with the messiness of daily life.
