This is a set of three books: "Management: Tasks, Responsibilities, Practices: Essentials" by Peter F. Drucker, "What If the High School Baseball Team's Manager Read Drucker's 'Management'?" by Natsumi Iwasaki, and "Who Moved My Cheese?". **"Management: Tasks, Responsibilities, Practices: Essentials"** This is a classic of management studies by Drucker, known as the father of modern management. It's a very helpful book for learning the basics of business. **"What If the High School Baseball Team's Manager Read Drucker's 'Management'?"** Commonly known as "Moshidora" (If Dora). This book features a unique setting where a high school baseball team manager applies Drucker's theories, making it easy to read even for those who are not fond of business books. It's a popular work that has also been adapted into an anime. **"Who Moved My Cheese?"** "Who Moved My Cheese?" is a parable that tells the story of "two mice" and "two little people" living in a maze, searching for cheese, and how they deal with change. When a large amount of cheese suddenly disappears, the story contrasts those who immediately start looking for new cheese with those who get stuck on why the cheese disappeared, simply conveying the importance of "not being afraid of change and acting quickly." All three books are recommended for those interested in business or self-improvement. They are in relatively good condition with no noticeable scratches or stains. Thank you.
