And yet when people got into the role play I watch how quickly people dissolved into win-lose with obvious consequences. People are people wherever you find them and the number of advance degrees someone has... has nothing to do with whether or not they have judgment or maturity or perspective or ethics, which brings me perhaps to the most impactful course I took when I was here. And I talked a lot about this in the book which is called readings in power and responsibility. It was literature. From throughout the ages but it was also a set of compelling stories about who people are and how they behave and that made a big impact on me. One of the most cogent pieces of career advises I ever gave was something I gave to one of my very first subordinates. And she was a young woman wrestling with a set of personal choices. She was an engineer, it was in 80s. She was trying to decide about the age-old work-life balance question and I said to her, "Never sell you soul, because if you do, no one will pay you back". Now that may seem like very touchy-feely advice for a bunch of hardcore scientist engineers.
