Leaders set a very clear path every day, in a thousand different ways, of what the people must attend to, inhibit, and keep it current in front of them.
If you are building a culture where honest expectations are communicated and peer accountability is the norm, then the group will address poor performance and attitudes.
In a very real way, ownership is the essence of leadership. When you are 'ridiculously in charge,' then you own whatever happens in a company, school, et cetera.
What happens with a lot of leaders is that their leadership style is like ADD; they are all over the place with different ideas. They could be driving one idea forward but then move on to something else too soon.
In the end, as a leader, you are always going to get a combination of two things: what you create and what you allow.
Part of executive functions is the ability to look to a goal deadline and assess where an organization is in meeting it.
