The builder’s greatest achievement may be making themselves less central.

It is uncomfortable to aim at your own decreasing importance. Centrality feels like value, and stepping out of the middle feels like loss. But a thing that cannot run without you is capped at your capacity and ends with your attention, so making yourself less necessary is often the most substantial thing you do.

Map where you are still the single point of failure and pick one to dismantle. Document it, train someone, or change the process. Do this a few times and the thing becomes durable.
