With my own team I'm steady and sure. But put me in a room with the senior leaders and something in me shrinks. I go quiet, I defer, I don't take the seat I've earned. The authority that feels solid everywhere else just drains out of me the second I'm the junior one.
More people experience this than they realize.
Your authority is solid with your team but vanishes when you're the junior person in the room.
