The immediate answer that comes to mind is 'humility.' Because you've got to be humble, and you've got to be coachable. . . . Later, when I was running training, we would fire a couple leaders from every SEAL Team because they couldn't lead. And 99.9% of the time, it wasn't a question of their ability to shoot a weapon, it wasn't because they weren't in good physical shape, it wasn't because they were unsafe. It was almost always a question of their ability to listen, open their mind, and see that, maybe, there's a better way to do things. That is from a lack of humility. . .
