Who Moved My Cheese? An Amazing Way to Deal with Change in Your Work and in Your Life, published on September 8, 1998, is a bestselling seminal work and motivational business fable by Spencer Johnson. The text describes the way one reacts to major change in one's work and life, and four typical reactions to those changes by two mice and two "Littlepeople," during their hunt for "cheese." A New York Times business bestseller upon release, Who Moved My Cheese? remained on the list for almost five years and spent over 200 weeks on Publishers Weeklys hardcover nonfiction list. As of 2018, it has sold almost 30 million copies worldwide in 37 languages and remains one of the best-selling business books. Story Allegorically, Who Moved My Cheese? features four characters: two mice, "Sniff" and "Scurry," and two Littlepeople, human metaphor, "Hem" and "Haw." (The names of the Littlepeople are taken from the phrase "hem and haw," a term for indecisiveness.) They live in a maze, a representation of one's environment, and look for cheese, representative of happiness and success. Initially without cheese, each group, the mice and humans, paired off and traveled the lengthy corridors searching for cheese. One day both groups happen upon a cheese-filled corridor at "Cheese Station C." Content with their find, the humans establish routines around their daily intake of cheese, slowly becoming arrogant in the process. One day Sniff and Scurry arrive at "Cheese Station C" to find no cheese left, but they are not surprised. Noticing the cheese supply dwindling, they have mentally prepared beforehand for the arduous but inevitable task of finding more cheese. Leaving "Cheese Station C" behind, they begin their hunt for new cheese together. Later that day, Hem and Haw arrive at Cheese Station C only to find the same thing, no cheese. Angered and annoyed, Hem demands, "Who moved my cheese?" The humans have counted on the cheese supply to be constant, and so are unprepared for this eventuality. After deciding that the cheese is indeed gone they get angry at the unfairness of the situation. Haw suggests a search for new cheese, but Hem is dead-set in his disappointment and dismisses the proposal. Meanwhile, Sniff and Scurry have found "Cheese Station N," and new cheese. But back at Cheese Station C, Hem and Haw are affected by their lack of cheese and blame each other for their problem.
