Value of Something 

A giant ship's engine broke down and no one could repair it, so they took it to a Mechanical Engineer with over 40 years of experience.

He inspected the engine very carefully, from top to bottom. After seeing everything, the engineer unloaded the bag and pulled out a small hammer.

He knocked something gently. Soon, the engine came to life again. The engine has been fixed!

7 days later the engineer mentioned that the total cost of repairing the giant ship was $ 10,000 to the ship owner

"What ?!" said the owner.

"You did almost nothing. Give us a detailed bill."

The answer is simple:

Tap with a hammer: $ 2

Know where to knock & how much to knock: $ 9,998

Lessons to Learn

The importance of appreciating one's expertise and experience ... Until

The words "it's easy" and "that's all", should be set aside. Why? Because maybe the experience is the result of struggles, experiments and even tears.

Like the picture above:

If i do a job in 30 minutes it's because i spent 10 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

(If I can finish a job in 30 minutes, it's because I spent 10 years learning how to do it in 30 minutes. You paid me for those 10 years, not 30 minutes).

This sentence reminds me of someone’s advice on respecting and wisely respecting the work of others.

There I also learned to see people ...

When they do not respect others, at the same time he has humbled himself.

Expertise and experience, that's expensive.

Unfortunately, our people still look down on that.
