Who Moved My Cheese is a great motivational book with a powerful message . This envisions a few way for how we can live our lives . In the book ,four characters--two mice and two humans ---live in a maze with cheese . Both groups are content wit what they have and do nothing but enjoy their routines . One day , they discover that all of their cheese is gone. The two mice are not surprised by what happened because they noticed the dwindling cheese supply . So they leave their home to search for new cheese . On the hand, the humans , Haw and Hem, deny the situation and do nothing about the consequences. Toward the end of the book , Haw finally finds a new place with cheese by overcoming his fears, but not Hem . The book teaches how to adapt to change quickly. As the book says , "The quicker you let go of old cheese , he sooner you can enjoy new cheese."
