Active waiting
Patience is waiting. Not passively waiting. That is laziness. But to keep going when the going is hard and slow — that is patience. The two most powerful warriors are patience and time.
—Leo Tolstoy (claimed, unverified)
I could have sworn the quote was different, and I've been misquoting it for weeks. Still, I'm not sure Tolstoy ever said this, so maybe it doesn't matter. I prefer my own version, anyway:
Waiting is productive. Not passive waiting—that's laziness—but active waiting.
