Your standard isn’t what you do on a good day. It’s what you still do when you slept four hours and lost.

A standard that only holds when conditions are good is a preference wearing a costume. The real measure is the floor, not the ceiling: what still happens when you are tired, beaten, and nobody would blame you for skipping it. That floor is what other people plan around, because it is the part that is predictable.

Decide what the smallest version of your standard is, the one you could hold on your worst realistic day. Make that the rule and let the good days go past it. Write it somewhere so the tired version of you cannot quietly renegotiate.
