Knowing where your limit sits isn’t weakness. It’s how you avoid snapping in public.

Knowing your ceiling is practical information, much like knowing how much fuel is in the tank. People who insist they have no limit are not stronger, they are simply going to find the limit at the worst possible moment and in front of other people. Naming it in advance keeps the failure small and private.

Work out where yours sits: how many hours, how many people, how many days without a break. Build the next fortnight to stay under it. Saying no early costs far less than coming apart later and explaining it afterward.
