Continuation of Igor Mann's bestseller: 57 more rules for life and business from number 1 in Russian marketing - from speed reading and co-marketing to franchising and corporate culture. Igor Mann continues to share his wealth of experience and knowledge about a wide variety of phenomena and areas of life. The book grew out of a column on Igor’s Instagram account, which allowed him to win an argument and “gain” 100,000 subscribers in less than a year.
