Who Moved My Cheese? by Spencer Johnson is a simple motivational story about four characters—Sniff, Scurry, Hem, and Haw—who live in a maze and search for “Cheese,” which symbolises the things people want in life, such as success, money, career, happiness, or security. One day, their Cheese disappears, and each character reacts differently. Sniff and Scurry quickly accept the change and search for new Cheese, while Hem refuses to accept it and waits for the old Cheese to return. Haw initially feels afraid but eventually accepts that change is unavoidable, learns from his experience, and ventures into the maze to find new opportunities. The book teaches that change is inevitable, and instead of fearing, resisting, or blaming others, we should accept change, adapt quickly, and be willing to explore new opportunities.
