How Social Media Annexes Your Cognitive Landscape

In my 2016 book, Deep Work, I proposed a strictly binary approach to social media: you should perform an honest cost/benefit analysis on the social media platforms in your life, and quit all services that don’t provide substantially more benefits than costs with respect to things you truly value.

 Understanding the Education Customer
