Offline Only
2017. ~ One minute read.
Do you want to be productive? Just go offline, because to maintain a constant connection to the internet is to maintain a constant connection to interruptions, both external and internal.
The external interruptions are legion and well-documented: you have a new message on Gmail, Slack, Twitter, Facebook, Instagram, Snapchat, LinkedIn. Friends, family, coworkers, and spammers: each have direct access to your precious attention.
Offline-only content would also force creators to think differently. Look at this page: there is not a single link, no footnote offering to distract readers. How many good articles have you left half-read because you chased a shiny underlined link? When you are offline, right here is the only place you can be.
I can already hear the groans: “But I have to be online for my job.” I don’t care. Make time. I bet the thing that makes you valuable is not your ability to Google something, but your ability to synthesize information. Do your research online, but create offline.
Now back to your regularly scheduled internet. Just remember to give yourself an occasional gift of disconnection. **ASIS{_just_Go_Offline_When_you_want_to_be_creative_!}**
