Alerts alert. That means they get your attention. That means they take your attention from whatever it was you were doing. That’s fine if the alert really is important and urgent. But for most of us, most of the time, it’s not. The thing we were doing is more important. So mute alerts, pause them, go into airplane mode. This is about reclaiming control of where your attention goes, and applies to email, Whatsapp, Slack, Skype, internal messaging services – everything. Going full-screen (F11 on a PC or ^ + + F on a Mac) is a fast, effective way of muting alerts. Another way is to change your status to ‘Do not disturb’ on your various communications platforms.
