The idea
Morning preparation in this tradition is rehearsal for contact. Marcus reminds himself he will meet difficult people and why they act as they do; elsewhere he argues himself into rising for the work of a human being. Both moves aim the mind at the day's actual demands.
Modern morning routines often optimise mood. Stoic prep optimises aim: what pressure is likely, which role it hits, which virtue it asks for, what you will refuse to sacrifice.
Keep it short. A preparation that requires forty minutes will lose to the day before the day begins.

Why this matters
Unprepared entry is how the first email dictates the moral weather until dinner.
Specific prep creates recognition: when the thing arrives, you have met it once already.
It also links to mortality and justice — the day is finite, and other people are in it.
