My preference

If I was one of these persons, I would like to be Frank Gilbreth, because his stopwatch like lifestyle is the lifestyle that I want to have. According to my perspective time is the most valuable thing. By using time efficiently, nothing can be unresolved or impossible to do. On the hand, his management genius can be seen on his family which includes a dozen of children. Controlling children especially in high numbers can be harder than managing a big factory. Hence, he was the one who is most impressed me and become one of my idols.
