The title seems cliché but the author goes through a solid set of reasons for leaving and, more interestingly, goes into other facets of your life that you can alter in order to inhibit an addition to technology.

I particularly like the section on controlling his smartphone, as I can obviously relate to having a group of low-value apps that I periodically check when I'm bored. If I can increase the amount I read by moving the Kindle app front and center vs Snapchat that seems like a no-brainer for a low-effort high-impact change.
