I always tell people, "There's a book on everyone." I get some of that book before I do anything. If I want to deeply understand someone's reputation, I'll talk to their friends, their former bosses, their peers, and I'll learn a lot about them. I want them to be trusted. I want them to be respected. I want them to give a s - -. Then there are the intangibles: physical and emotional stamina, the ability to confront issues. I can ask all I want about those things, but I also have to see a lot of it.
