Read this sharp Sharkonomics review from the US tour in Chicago.

…nature works @ a higher level than strategy.  The problem with reading books & implementing what you read is that they require deep dives into research, which takes a lot of time.  When you finally see a sign that there’s a shark behind you, it’s too late to do anything about it & it eats you up.
