Check out the most recent (August 26/2016) TED Radio Hour podcast (a synthesis of some of the topics from a variety of TED Talks from around the world) about slowing down. It talks about the boost to creativity that happens when we slow down. And also looks into the brain of extreme procrastinators to see what we can learn. And what about the gain from writing letters by hand?
Also - "Slow TV" - how about watching the video from the front and sides of a four hour train ride; millions of Norwegians (and many others) are doing just that.
Bottom line is the gain we can experience in slowing down. We are designed to need rest, and when the brain gets good breaks, distractions and diversions our productivity and creativity go significantly up.
