Here is the test to find whether your mission on earth is finished: if you're alive, it isn't.
Bach isn't simply saying you have work to do—he's dismantling the false comfort of "finding your purpose" as though it were a destination you could reach and then rest. Most people wait for clarity to arrive fully formed, imagining purpose as a completed blueprint they'll someday recognize; Bach suggests instead that the very act of being conscious is itself the assignment, requiring constant renewal rather than eventual completion. A person might spend years perfecting a career only to discover that the real work was the daily choice to show up with intention, not the arrival at some imagined finish line. This reframes frustration (why can't I pin down my calling?) into something more honest: you're meant to keep becoming, not to arrive.
