Life's Lessons: Right effort makes all the difference

Then they brought in an old man who had been fixing engines since he was young. He had a large bag of tools and immediately set to work. He looked at it carefully, reached into his bag and pulled out a hammer.  

He gently tapped on it and the engine sprang into life. A week later, the owners received a bill from the old man for Rs 10,000. 

“What?!” the owners exclaimed. “He hardly did anything!”  So, they wrote a note to the old man, “Please send us an itemised bill.” 

The man sent a bill that read: Tapping with a hammer- Rs 2. Knowing where to  tap - Rs 9,998.   

Moral: Effort is important, but knowing where to make it in your life, makes all the difference.
