I read it long long time back, somewhere when I was in class six.
There was a mouse, who used to be in constant distress because of its fear of the cat. One fine day, a magician named Rahim, took pity on it and turned it into a cat. But then it became afraid of the dog. So the magician turned it into a dog. Then it became to fear the panther. So the magician turned it into a panther. Whereupon it was full of fear of the hunter. At this point the magician gave up. He turned it into a mouse again saying, “Nothing I do for you is ever going to be of any help because you have the heart of a mouse.”
Remember: Everyone is your best friend when you are successful. Make sure that the people that you surround yourself with are also the people that you are not afraid of failing with. Period.
