At some point in the last decade, we made an unspoken agreement that being reachable at all times is a reasonable expectation.
This expectation is new. As recently as the early 2000s, it was perfectly normal to be out of contact for hours or even days at a time. Nobody expected a same-day response to a letter. Voicemails could sit for a day without anyone thinking you were dead or angry. The idea that you would be available for instantaneous contact during every waking moment would have seemed bizarre.
What changed wasn't just technology. Technology made constant availability possible. Culture made it expected. And that expectation is quietly damaging our ability to do our best work, maintain our most important relationships, and preserve our mental health.
The cost of constant availability is measured in attention. Every time you're reachable, you're also interruptible. And every interruption, even a brief one, carries a cognitive cost that extends well beyond the interruption itself. You don't just lose the seconds it takes to read a notification. You lose the minutes it takes to re-enter the cognitive state you were in before the interruption. Over the course of a day, these micro-interruptions add up to hours of lost deep work.
The people who produce the most valuable creative and strategic work have figured this out. They've become strategically unreachable, not all the time, not rudely, but deliberately. They have hours of the day when their phone is in another room. They have days when they don't check email. They have boundaries that they communicate clearly and enforce consistently.
The key word is "strategically." This isn't about becoming a hermit or being unresponsive to genuine needs. It's about recognizing that availability is a resource, not a virtue, and allocating it accordingly. You wouldn't give every project the same budget. You shouldn't give every relationship and every communication channel the same access to your attention.
The practical implementation is simpler than people think. Start by identifying the two or three hours of your day when your cognitive performance is highest. Protect those hours fiercely. No messages, no meetings, no calls. Then communicate this boundary once, clearly, to the people who need to know. Most people will respect it. Some will even admire it. And the quality of work you produce in those protected hours will be noticeably, measurably better.
