How can we survive in the modern world? Bestselling author Jordan B. Peterson humorously, surprisingly, and informatively answers this question. He explains why we should let children skateboard alone, what cruel fate befalls those who criticize too quickly, and why we should always pet cats we encounter on the street. But what does the nervous system of a lobster tell us about our chances of success in life? Dr. Peterson discusses concepts such as discipline, freedom, adventure, and responsibility, condensing the truth and wisdom of the world into 12 practical life rules.
