A giant ship’s engine broke down and no one could repair it, so they hired a Mechanical Engineer with over 30 years of experience.

He inspected the engine very carefully, from top to bottom. After seeing everything, the engineer unloaded his bag and pulled out a small hammer.
He knocked something gently. Soon, the engine came to life again. The engine has been fixed!

A week later the engineer mentioned to the ship owner that the total cost of repairing the giant ship was $20,000.

“What?!” said the owner. “You did almost nothing. Give us a detailed bill.”

The Engineer replied him “The answer is simple:”

Tap with a hammer: $2

Know where to knock and how much to knock: $19,998

The importance of appreciating one’s expertise and experience…because those are the results of struggles, experiments and even tears.

If I do a job in 30 minutes it’s because I spent 20 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.
