This is a very abbreviated form as I'm heading out the door, but typically a "leader" is more likely to be lower on agreeableness than a "manager". It's a component of pushing boundaries or navigating challenges/obstacles. A "manager" biases higher on conscientiousness than a "leader" because their role as a facilitator is in no small part to make sure all the i's are dotted and the t's are crossed.

Likewise a good "manager" is probably motivated by community-building and completion. A good "leader" is probably motivated by the challenge and the path itself in addressing it.

Now, to the airport!
