my favorite pillar is number 4: groundedness. I think great leaders realize that they are made of more than leadership. They hold value in more than what they lead. Groundedness means balance in life. Being a good dad, good husband, good neighbors and caretakers, good tenants, good shoppers and so on.
A good leader understands we are more than 8 hours we put into work. We have all been somewhere, are going somewhere and we are here.
