Before tough meeting, declare boundary: "I have only 30 minutes".

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

Pick three tasks that make today a success regardless of anything else, and finish them before noon.

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

Repeat the same refusal in the same words calmly, no matter how the other person reshapes the pressure.

Say no in three sentences: thanks, refusal, closing — with no "sorry" or justification.

Memorize one 7-word refusal sentence and rehearse it until it emerges automatically under pressure.

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

Pre-decide a clear start and end time with yourself before any draining family visit.

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

When he opens sensitive topic, say "tell me more" vs reply.

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

At any moment, one tab, one window, one task — multitasking is a neural myth.
