A day entered calmly can still become difficult without making the calm preparation worthless.

Preparation is not a promise about outcomes. A steady start does not prevent bad news, and when a day goes wrong anyway it is tempting to conclude the quiet hour was wasted, which is the wrong lesson to take. What that hour bought was the state in which you met the difficulty, and that is not nothing. You never see the version where you began ragged.

Keep the small settling routine even in the week it appears not to be working. Judge it by how you handled things rather than by how things went.
