Marcus tells himself to focus on the transience of the events in the grand scheme of things. He suggests contemplating the fact that both he and the person with whom he’s angry will eventually be dead and forgotten. When viewed from this perspective, it doesn’t seem worth getting flustered by people’s behavior. Nothing lasts forever. If events will seem trivial in the future when we look back on them, then why should we care strongly about them now? This doesn’t mean that we should do nothing. Indeed, by remaining calm, we can plan our response better and take action.
