Older, plainer

Book Seven marks a tonal shift in the Meditations. The early books had set pieces — the morning warmup of Book Two, the inner citadel of Book Four, the portrait of Antoninus in Book Six. From Book Seven on, the writing thins. The fragments are shorter; the tone is plainer; the exercises repeat more often.

Marcus is also older. He notes it. "How short a time you have left," he tells himself. The exercises are less developed and more direct. Death, the brevity of fame, the cosmos as one rational thing, the discipline of assent — these are now stated almost as reminders, in single sentences, sometimes barely a clause. The reader feels Marcus picking up his notebook in passing, jotting a single line, and putting it down.

The book contains some of the most quoted simple formulations in the work. "Do not be ashamed to be helped — it is like a soldier scaling a wall." "It can ruin your life only if it ruins your character." "Don't fire the second arrow." Each of these is a small Stoic exercise compressed to a sentence. By Book Seven Marcus has been doing the work long enough that the long formulations are no longer needed. He just needs the prompts.
