Consistency does not require identical days.

Consistency gets confused with sameness, and the confusion is expensive. If your standard requires every day to look alike, then travel, illness, and a hard week all count as failure, and the whole structure collapses under conditions that were always going to arrive. What holds is the direction, not the shape of each day.

Define your commitment by what stays true rather than by what stays identical. Ask what the smallest honest version of this looks like on a bad day, and decide that it counts. That decision is what lets the thing survive the year.
