Self

This is the foundation of everything else. It's the only thing you have direct control over. It's the most important because this is the area that will affect everything else. If you don't get this right then everything else will be an uphill battle, almost impossible.

As a Leader you need to be as good (or better) than the people you lead. If you have a "Do as I say not as I do" attitude then you're not a leader, you're a boss.

Working on yourself is essential.
