Query: Groundbreaking

Reading this book was a breath of fresh air! Michael Lewis is able to show how rational and objective thinking can be applied to all areas of life, business and even in baseball. Narrated in the manner of a novel, it engaged me to a point that I couldn't put it down. I finished the book in 3 days, that's how engaging it is! I pride myself in being rational and objective as possible, but this book was able to motivate me to push those facets even further, especially in applying math and statistics to objectively find out rational solutions.
