The document summarizes the story "Who Moved My Cheese" which uses the metaphor of mice and humans to illustrate how to successfully adapt to change. It describes the four characters - Sniff and Scurry, the mice who easily adapt to changes in the location of cheese, and Hem and Haw, the humans who struggle with change. When the cheese station is moved, Sniff and Scurry quickly find new cheese while Hem refuses to accept the change and Haw eventually learns to adapt. The lesson is that one must accept that change happens and be prepared to adapt to new circumstances.
