Query: John Boyd, Genius and Hero, magnificent book

Fascinating insight into the mind of a genius. I read it in one day and did not want it to end. Boyd was fascinating. The book explains how he approached and solved complex problems. It explained how he made himself and coworkers more creative & productive. An interesting perspective on the concept of "thinking outside of the box". These strategies are very useful for problem solving eg. to test a theory, he recommends to extrapolate it out to the extremes in both directions as this often clarifies if it truly makes sense.
