A set of 4 books offering practical knowledge on business and achieving goals: - Title: The Divine Skill of Goal Achievement Author: Keisuke Baba - Tokyo University Style Goal Achievement Thinking Author: Shogo Aio - Title: The Strongest Way of Working Author: Mooki Kim - Title: The Conditions for Leaders Who Produce Results Author: Koichiro Yoshioka Thank you for viewing. "The Strongest Way of Working" has some wear and tear on the cover, but the others are in good condition. The contents of all the books are clean. The original price would be over 5,000 yen in total. I think it's a great value set. I look forward to hearing from you. Thank you.
