Writing benefits most from focused thinking, because writing is organized thought. The less clutter to rob you from working, the more work gets done.
If you could remain focused for a long stretch of time, say from 8 AM to 5 PM, how much would you accomplish? How much further down the checklist would you be? Would there even be a checklist anymore?
Life under the hypnosis of social media, TV, pointless relationships, etc. is a road leading to nowhere, filled with all the pointless-nothing you could ever ask for, all in exchange for your time.
