The military is not different than business, it's not better or worse than business. The lessons are just much easier to see because the stakes are higher. In other words, everything is exaggerated. So the good is really good and the bad is really bad, and the impact of really good is obvious, and the impact of really bad is obvious. And so, I find that it's a much easier place for me to study leadership, just because it's way exaggerated. Right. The other thing is it's a deeply human culture, because the stakes are life and death, very often. And so in business, we have colleagues and co-workers. They have brothers and sisters, it feels really different.
