Written by Spencer Johnson, Who Moved My Cheese? is an internationally acclaimed business and personal development classic that uses a simple but powerful story to teach readers how to respond positively to change. The book follows four characters, Sniff, Scurry, Hem, and Haw, as they navigate a maze in search of cheese, a metaphor for the things people want in life, such as success, security, relationships, money, or happiness. When their cheese suddenly disappears, each character responds differently. Through their experiences, Johnson demonstrates how fear, resistance, and attachment to familiar routines can prevent people from moving forward, while adaptability, awareness, and willingness to take action can create new opportunities. The book encourages readers to anticipate change, recognize when circumstances have shifted, let go of outdated expectations, and confidently search for new opportunities. Its lessons can be applied to careers, businesses, relationships, personal goals, and everyday challenges.
