A World Without Email | Cal Newport

The book by Cal Newport,  "A World Without Email" is his attempt to tackle the crisis of focus and communication overload. To pull together—for the first time—everything we now know about how we ended up in a culture of constant communication, and the effects it’s having on both our productivity and our mental health, as well as to explore our most compelling visions for what alternative forms of work might look like.  

The key is to find ways to minimize context shifts and overload while still getting done what needs to get done.                                                      

When you have a say in what you’re doing (placing the locus of control toward the internal end of the spectrum), you’re much more motivated than when you feel like your actions are largely controlled by outside forces (placing the locus of control toward the external end).
