Your habit should know how to survive travel, stress, and inconvenience.

Most habits are designed for the ideal version of your week, which is the version you will rarely have. A habit that requires your own kitchen, an hour, and a settled mind is a habit that dies on the first trip and the first stressful month. Durability comes from designing for the difficult conditions rather than the pleasant ones.

Ask what this looks like in a hotel room, on four hours of sleep, or in a week you did not choose. If there is no answer, invent one now. The portable version is what carries the habit through the year.
