Remove ambient interruptions

Eliminate the notifications and open channels that force micro-switches.

Why it works

Every notification is an involuntary switch cue: even dismissed, it pulls attention and starts a switch you then have to reverse. Removing the cues removes the switches before they happen, which is far cheaper than resisting each one. Self-interruption follows external interruption, so cutting the inputs cuts both.

How to do it

1. Silence non-urgent notifications and close messaging apps during focus blocks.
2. Put the phone out of sight, not just face-down — visible cues still cost attention.
3. Set a "I’ll check at [time]" expectation so you are not pulled by the fear of missing something.

Evidence

Studies of interrupted work show interruptions increase completion time and error/stress, and people often self-interrupt nearly as much as they are externally interrupted. (observational)

Field-study correlations are strong but context-dependent; exact time costs vary by task and person.

Common mistake

Leaving notifications on but planning to "just ignore them." The cue still fires a switch; the only reliable fix is removing the cue.
