Koh Younghoon, a board member of the Korean Association for Public Interpretation and Translation (professor at the College of Occidental Languages, Hankuk University of Foreign Studies) published a translation of Small Habits Revolution on January 16, 2020. The book is the most practical book on small habits. Damon Zahariades, the author of the book and America's top productivity expert, introduces various ways to create the most efficient daily life and work to various media outlets. This book contains only practical content for optimal efficiency in itself. It excludes the theory of habit-related brain science, psychology, behavioral theory, or how to break bad habits, and deals with only the core of rapid practice, from how to make good habits to how to maintain habits without wavering internal and external resistance. Thanks to its targeting of the desire of modern people who have a lot of things to do but lack time, this book has been a bestseller in Amazon's independent publishing for more than three years.
