Leadership is leaving people with more confidence in themselves, not merely more admiration for you.

Admiration flatters the leader and does very little for the person feeling it. Confidence in themselves is harder to build and is the thing they can actually use, particularly once you are no longer around. The two often get confused because both look like a successful relationship.

Notice whether people leave conversations with you feeling impressed by you or capable themselves. Aim for the second. It requires saying less and asking more, and it holds up much better over time.
