Spencer Johnson's book "Who Moved My Cheese?" uses the metaphor of mice (representing people) searching for cheese (representing what one wants in life) in a maze (representing where one looks) to teach lessons about dealing with change. The story follows four mice - Sniff, Scurry, Hem and Haw - who discover their cheese has been moved and must adapt to the change. Haw ultimately learns to accept and embrace change rather than fearing it. The book recommends anticipating and adapting to change quickly in order to keep finding what you want in life.
