I confess that I have been reading The Luminaries (a book about 19th-century New Zealand written in the language of the same) since Christmas, but until now I have only been able to handle a chapter a day. It's a very dense book and at 830 pages long, I was worried that I would never finish it. Or understand it if I did. I'll be glad to finish it and get on to something lighter for a while.
But yes, spending less time on Facebook, twitter, LinkedIn and Instagram means that I have more time to focus on my Deep Work and I have more time in the evenings to read. It also means that I don't have the anxiety that comes with not posting to Facebook and not checking for any posts I may have missed. I know I'm missing everything, but strangely I feel a lot calmer about it than when I was checking it every day. If you don't know what you're missing you have a lot less FOMO.
