Yep, a very interesting topic!
I have met people in different places that I have worked that just put me in awe. I feel like I am very knowledgeable in my career, and I am confident in myself, but I also realize I do not know everything.
I have met people that seem to know everything, or in other words, they are so confident that whatever they say turns to gold. These charismatic people, with indefinite knowledge, have always amazed me. They may not be as good looking as Harvey, or make as much money, but they are very much on his level in their own way.
