A lot of what I've read about the attention economy revolves around tweaks to existing technology, employing more technology to counteract perceived problems of technology and social media, or wish lists saying how nice it would be if things were designed differently.

I found this book refreshingly different. Although it's written by a technologist, it concentrates much more on healthy and productive use of existing technology rather than messing about with tweaks (turn off your notifications ect). I especially like how its arguments are given historical context with reference to people such as Abraham Lincoln and David Thoreau and what they teach us about concentration and distraction.
