Yeah.. I can see where you're coming from and can agree to a certain extent BUT the guy is trying to change the energy industry.. oil and gas.. You've got to have some tenacity and ego to even make a dent in that sector. Point it.. his current success is in large part due to his polarizing personality, not despite it. Only opinion of course, and I may be wrong but I just think that some meek, humble, personality wouldn't be able to lead such an endeavor very effectively.
I'm sure you could dig up countless examples of the opposite of my point but hopefully you see where I'm coming from.
