What does it mean that the minimum viable routine?

Have a stripped-down version of every important routine that works during disruptions.

Example: Your morning routine at home is a forty-five-minute sequence: wake at 5:30, ten minutes of meditation, fifteen minutes of journaling, a twenty-minute run, and a cold shower. It works beautifully in your own house with your own equipment on your own schedule. Then you fly to a conference. The hotel room is small, the walls are thin, the gym opens at 7:00, and your first session starts at 8:00. You have maybe twenty minutes. Without a pre-designed minimum viable version, you face a binary choice — execute the full routine (impossible) or skip it entirely (demoralizing). You skip it. You skip it the next morning too. By the third day you have stopped thinking about the routine at all. But your colleague in the next room faces the same constraints and does something different. She sits on the edge of the bed, closes her eyes for two minutes, writes three sentences in the Notes app on her phone, and does ten bodyweight squats. Seven minutes. She does not pretend this is equivalent to her home routine. She knows it is not. But she also knows that the purpose of her morning routine is not the specific actions — it is the cognitive reset that separates sleep from work. Seven minutes achieves that reset. Zero minutes does not. She has a minimum viable routine, and you do not, and that single difference means she returns home with her behavioral system intact while yours needs to be rebuilt from scratch.

Try this: Choose your most important daily routine — the one whose absence you feel most acutely. Write down every action in the full version with approximate durations. Now identify the essential function of that routine — not what you do, but what it accomplishes for you (cognitive reset, physical activation, emotional regulation, creative priming, or whatever the honest answer is). Strip the routine to the fewest actions that still deliver that essential function, with a total duration under ten minutes. Write this minimum viable version on a card or in a note you can access anywhere. Tomorrow, execute only the MVR — even though your full routine is available — and assess whether the essential function was preserved. If yes, you have a valid MVR. If not, the function you identified was wrong or the actions you kept were the wrong ones. Revise and test again.
