“Do what you have in hand justly, now, and let the rest go.”Marcus Aurelius · Gânduri către sine · 180 · Cartea VII, 20
Marcus Aurelius, an emperor writing private notes to himself, builds on a Stoic distinction: we control only our own judgment and action, never outcomes or the future. The mechanism is relief through focus, since the mind cannot ruminate about tomorrow while working concretely now. A clerk anxious about a boss's decision can still write today's report carefully and honestly.
Why it matters Anyone overwhelmed by long task lists or worries about the future can use it as a filter: one thing, done well, now.
