Query: Lacked focus on importance

If you going to attempt a 180 page biography of someone of this stature, one must sift thru and present only the most relevent and important details. This did not happen. A decent book, but lacked details on some very important areas, while giving too much time to unrealted topics. Example: Mao becomes the head of a small, isolated band of communist guerilla fighters. Very well, now how does he transform from that, into the head of state for a billion people? the book doesnt say. In this biogarphy, Mao goes from that cave-living nobody into meeting Stalin and ruling China in about 2 paragraphs. From cave-dweller to world leader in 6 sentences. We get more than 6 sentences about his last secretary's personal life.
