Know Your Value.

A giant ship's engine broke down and no one could repair it, so they hired 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 $20,000 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 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.
