This is one of my favourite Korean reads yet - not just for non-fiction. The author knows what he is talking about and references his own personal experiences. I enjoy the small bits of humor he adds to his writing throughout. Parts of the book are extremely repetitive as he gives recommendations for shows to watch or books to read for Koreans learning English, however I still found them worth reading. The vocabulary is fairly limited to but he does use longer sentences than other non-fiction books like 미친 집중력.
