"Quiet" is not a synonym for "weak."
In leadership, we tend to associate quietness with passiveness.
Leaders need to be loud, assertive, brash, and strong.
In reality the leaders I know who are quiet on the inside (settled, grounded, confident) are often the strongest and most effective.
The loudest person in the room is often the person LEAST likely to read the room, listen to the room, learn from the room or LEAD the room.
Of course there's a time to speak up, take charge, and give directives. But more often than not, leaders would benefit from being quiet.
Quiet on the inside.
Quiet on the outside.
