Hack Back External Triggers
Ask one critical question about every ping, ding, and interruption: Is this trigger serving me, or am I serving it?
Hack Back External Triggers is a systematic audit-and-eliminate approach to the environmental cues that pull you off track. The core principle is that not all external triggers are bad — some lead to traction. The critical question for every trigger is: 'Is this serving me, or am I serving it?' Eyal provides specific tactics for eight categories of external triggers: work interruptions (use visible 'do not disturb' signals), email (batch processing, slow responses, labeling), group chat (use it like a sauna — in and out), meetings (reduce and restructure), smartphone (four-step cleanup in under an hour), desktop (remove clutter and notifications), online articles (save to Pocket, read later via multichannel multitasking), and social media feeds (eradicate or bypass feeds entirely). The approach draws on hospital research showing that reducing interruptions during medication dispensing cut errors by 88%.
- Not all external triggers are harmful — the critical question is whether each trigger serves you or you serve it
- Interruptions don't just waste the time of the interruption — they fragment attention and increase errors
- Technology should serve us, not the other way around
- Removing visual clutter and notifications reduces the psychological toll on attention
- Multichannel multitasking (pairing audio content with physical activity) can turn wasted time into traction
- Audit all external triggers with the critical questionGo through every notification, alert, and environmental cue in your life and ask: 'Is this trigger serving me, or am I serving it?' If a trigger leads to traction, keep it. If it leads to distraction, eliminate or modify it.Pro tipStart with your smartphone — Eyal's four-step phone cleanup takes less than one hour and yields the biggest immediate benefit.
- Hack back work interruptionsUse visible signals to prevent others from breaking your focus. Place a screen sign ('I need to focus right now, but please come back soon') on your monitor. Discuss the practice with colleagues so they understand and potentially adopt it too.Pro tipJust as hospitals adopted 'sterile cockpit' rules from aviation, create focused work zones or time blocks where interruptions are not permitted.
- Hack back digital triggersTurn off all non-essential notifications on phone and desktop. Remove distracting apps from your home screen. Use browser extensions to eliminate social media feeds (News Feed Eradicator, DF Tube). Save articles to a read-later app (Pocket) instead of reading them immediately. Set devices to permanent Do Not Disturb.Pro tipUse 'temptation bundling' — pair saved articles with exercise by listening to them via text-to-speech while working out.
- Hack back meetings and group communicationReduce meeting frequency and duration. Require agendas. For group chat, treat it like a sauna — get in, get the information, get out. Batch email processing into scheduled timeboxes rather than checking continuously.Pro tipSet email response expectations by slowing your response times deliberately — people will adjust their expectations to match your cadence.WarningDon't eliminate all external triggers. Some (like calendar reminders for scheduled tasks) serve traction and should be kept.
Nurses wearing bright orange vests while dispensing medication saw a 47% reduction in errors in the initial trial. When expanded across multiple hospitals with additional measures like 'sacred zones' and distraction-free rooms, errors dropped by 88% over three years.
Instead of reading articles in the browser (which led to tab-hoarding and hours of distraction), Eyal saves everything to Pocket and listens to the articles via text-to-speech only while exercising or taking walks.
Eyal was inspired by nurse Becky Richards at Kaiser Permanente, who proposed that nurses wear bright orange vests while dispensing medication to signal they should not be interrupted. Despite initial resistance (the vests were 'cheesy' and hot), the practice reduced medication errors by 47% in the test unit. Expanded across multiple hospitals using 'sacred zones' and distraction-free rooms, a coordinated study found an 88% drop in errors over three years. The principle was borrowed from aviation's 'sterile cockpit' rule, which bans noncritical activities below 10,000 feet.
