Do yourself a favor: kill the notifications off. Don’t participate in the notification economy. Change your relationship from passive to active. Instead of relying on Facebook to command your attention, schedule a meeting with it. If Facebook’s important to you, put 15 minutes on your calendar for it and make that the time that you check Facebook. Kill everything you can with a number by it. Eliminate anything you can that makes a noise that might tempt you into giving your attention away.
