"Who Moved My Cheese?" is a parable written by Spencer Johnson, M.D. that tells the story of four characters living in a "Maze" who are searching for cheese, a metaphor for what we want in life. The four characters are two mice named Sniff and Scurry, and two "Littlepeople" (human-like creatures) named Hem and Haw.
Sniff and Scurry are mice who are always on the lookout for cheese and are willing to take risks in order to find it. They are proactive and adaptable, and when they realize that the cheese they have been relying on has run out, they quickly move on to find more.
Hem and Haw, on the other hand, are Littlepeople who are more resistant to change. Hem is particularly resistant, clinging to the old ways and refusing to believe that the cheese has run out. Haw, on the other hand, is more open to change and is willing to explore other options.
As the story unfolds, Sniff and Scurry are able to adapt to the changing circumstances and find new sources of cheese, while Hem and Haw struggle to come to terms with the fact that their cheese has run out. Eventually, Haw is able to overcome his fear of change and adapt to the new situation, while Hem remains stuck in his old ways and fails to find new sources of cheese.
The parable of "Who Moved My Cheese?" is a powerful reminder that change is a constant part of life and that we must be willing to adapt and explore new options in order to be successful. It encourages us to embrace change, be proactive, and take risks in order to find what we want in life.
