This is the best use of a fictional character to convey solid business principles that I've seen since the book Make it So: Leadership Lessons from Star Trek: The Next Generation. I'm going to share it in some other places.

That said, I wish you could have worked into it somehow Tyrion's love of reading, which is explained by one of his best quotes: "My brother has his sword, and I have my mind. And a mind needs books like a sword needs a whetstone: to keep it sharp."
