Say "no, I can't" — complete sentence. No explanation, no apology.

Define where your "good enough" is on a 0-100 ruler, to know when to stop.

Sort tasks on urgent/important axes and treat each quadrant with its rule.

Do not commit on the spot. Request 24 hours to think before any new obligation.

Delegate each task at one of five explicit levels instead of just "do it" or "don't".

Specify the decision-types (not tasks) you will delegate via an explicit authority ring.

Decline any meeting without a written agenda — politely cancel and request one.

Per decision type: who proposes, decides, consulted, informed.

In crisis: one person leads, all report to them, fast decisions — not "committee".
