Define an async charter with your team: when to reply, how, and what counts as "urgent".

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.

Invent at least three plausible reasons for a behavior that upset you, before you judge.

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

Compute colleague's time before writing, use schedule-send to avoid sleep disruption.

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

Before confirming a decision, spend 10 minutes writing the counter-case forcefully.

Who influences whom? — draw network to know "who talks to whom to shift decision".

Your quick intervention to stop every squabble robs your children of learning to solve it themselves — deliberate delay beats over-hasty intervention.
