who wrote the following statement on the wall if you don't change you become extinct
Who Moved My Cheese? 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. Hoping to change, Haw again proposes a search for new cheese. However, Hem is comforted by his old routine and is frightened about the unknown. He knocks the idea again. After a while of being in denial, the humans remain without cheese. One day, having discovered his debilitating fears, Haw begins to chuckle at the situation and stops taking himself so seriously. Realizing he should simply move on, Haw enters the maze, but not before chiseling "If You Do Not Change, You Can Become Extinct" on the wall of Cheese Station C for his friend to ponder.
