I value my time greatly. The author repeatidly voiced his belief that scientists are stubborn creatures unwilling change directions unless bludgeoned repeatedly by an outside force. This wasted much of my time. But, I am not a scientist. I found the repetition painful. However I have gleaned many valuable insights from the book. I would recommend it to all, scientist or not as it will help clarify your thoughts and communication. * Needs a pdf to accompany it.
