Why does it feel like I'm the one holding everything up?

You can look at a plan, a team, a system, and see exactly where it will crack. Most people cannot do this. It is a real skill, and it has made you the one everyone leans on. But you have quietly decided that if you stop checking, it falls. That no one else sees what you see. That is not humility — it is a claim about other people you have never tested. Test it. Working with others does not mean doing it more gently alone. It means giving away a piece of the load and finding out — not assuming — whether it holds.
