Thanks, @shubham346verma recommending and sharing this book.
"Who Moved My Cheese"written by "Spencer Johnson" llustrates many instructive lessons, that anyone can apply to your their life.
I felt myself in the character of *Hem*, but now I will change my self into Haw.
This is a fictional book having four characters, two mice sniff and scurry and two little people Hem and Haw.
All these characters are having different perspectives and different ways of gaining success or Cheese. Actually we all have same perspectives towards life. And these perspectives towards success makes us successful. I found myself like Haw. I always feel myself comfortable in static life or position. But whenever I tried to come out of that zone. I found myself more happy and successful. If you are too afraid of things that will happen if you change, be the change.
