Try a standing rule: “No meetings before noon on Tuesdays and Thursdays.” Add “two ninety-minute deep work blocks daily, phone in another room, door sign on.” Protect these blocks as if they were external appointments, moving them only with explicit tradeoffs. When interruptions arise, a polite script and calendar evidence help you defend boundaries kindly. Over weeks, focused blocks become cultural artifacts colleagues learn to respect without friction or drama.
Set simple hours: morning, midafternoon, late day. Outside those windows, close the inbox entirely. Use brief rules: archive newsletters automatically, star stakeholders, batch replies with short templates, and escalate only after two clear attempts. A signature line that names your checking windows educates others and reduces anxiety. Paradoxically, fewer checks improve reliability because responses happen deliberately. The inbox becomes a queue you manage, not a slot machine you fear.
