There is no evil in things changing, just as there is no good in persisting in a new state.Marcus Aurelius, Meditations, 4.42
Events are neither good or bad. They just are. In fact, they are objectively pure. The universe does not actually have an agenda since it is primarily a physics simulation.
The book notes that the Stoics would remind everyone of this fact. The status quo is not inherently good and change is not inherently bad, and the reverse is also true. The goal, then, is to make the most out of every situation.
Accept what is and adjust your attitude accordingly.
