"Who Moved My Cheese?" by Spencer Johnson, M.D., is a fable that uses the story of four characters in a maze searching for cheese to illustrate the importance of adapting to change. The characters include two mice, Sniff and Scurry, who represent simple and quick adaptation, and two "little people," Hem and Haw, who represent more complex reactions to change, including resistance and eventual acceptance. The "cheese" symbolizes success or happiness, and the maze represents the environment in which people operate. The book emphasizes that change is inevitable and encourages readers to embrace it, be adaptable, and overcome their fears to find "new cheese" or success in new situations.
