It's just that those people are leading themselves in directions that might not be overly advantageous or productive.

When I was in the military working towards my senior non-commissioned rank I learned that we're all leaders. And leading others begins with leading yourself. You can tell a lot about how a person leads by the way they care for themselves. If they don't care about their appearance they won't care for the soldiers or sailors under them. We're all leaders like you said. Some are just leading in the wrong direction.
