Who Moved My Cheese was a rather interesting look at the personalities involved with change. The book actually does not have anything to do with cheese, the cheese is a metaphor for whatever you want it to mean.
The book has four primary characters, two mice named Sniff and Scurry and two little people named Hem and Haw. These characters all live in a world where they enter a maze everyday to look for cheese to eat. The two groups do not work together; they take separate routes through the maze in search of their cheese.
The two mice use a peculiar process, Sniff sniffs the air trying to get a whiff of cheese and when he smells it Scurry runs in the direction Sniff smells the cheese. Through trial and error they inevitably are successful and more efficient than the little people. When they find cheese, they keep track of the amount of cheese and its condition, they mentally prepare to resume their search for cheese when the inevitable occurs.. When they discover that the cheese has gotten old and the supply has run out they simply take the facts as they are and go off in search of some new cheese, they don’t question the problem, they simply see the situation for what it is and take appropriate action. Eventually they find new cheese and are happy.
The little people approach life from a different perspective. They also find the first cheese and take it for granted that it will be there everyday since there is such a large amount. They do not take the time to check it out, like the mice do, and never see that it is shrinking in amount and that it is also getting old.
When the cheese inevitably runs out, they are in denial and refuse to take action. They go home and return, only to find no cheese. Haw desires to get on the move and get into the maze and find some new cheese, but Haw refuses because he is scared. They start to starve, but still do nothing. Finally, Haw decides to take action and he leaves on his own.
Haw goes into the maze and...
