A bad boss can make your job bad even in a very good company – they will micromanage you, blame you, and make your life miserable.
A good boss will stand up for you, will trust you, will listen to you, and will make yours a good job even in a weak company.

Go where you are celebrated, not just tolerated.
If they do not see the real value of you, it’s time for a brand new start.
If you dread Mondays, and your favorite F-word is Friday, then perhaps it’s time to answer the call of a recruiter.

Leaders that do not see values of talent, hard-work, and loyalty in their employees do not last, anyway.
A job of a leader is to recognize the value of their people, and encourage them accordingly with PRIDE:

“Many of life’s failures are people who did not realize how close they were to success when they gave up” Henry Ford
“The main difference between success and failure is pure perseverance.” Steve Jobs
“Perseverance is failing 19 times and succeeding the 20th.” Julie Andrews
Which is why you will be successful ! Because you persevere, AND you appreciate others who do the same.
You may think your progress is slow, but look back and see how far you traveled.
I am so inspired by people who get up, show up, give it all he got and never give up.
Work hard. It is better to be tired than disappointed.

There is also a lot of difference between petrol and diesel engine and these are as follows:
| S.No | Petrol Engine | Diesel Engine |
| 1. | The petrol engine works on Otto cycle i.e. on constant volume. | The diesel engine works on diesel cycle i.e. on constant pressure. |
| 2. | The air and petrol are mixed in the carburetor before they enter into the cylinder. | The fuel is fed into the cylinder by a fuel injector and is mixed with air inside the cylinder. |
| 3. | The petrol engine compresses a mixture of air and petrol which is ignited by an electric spark. | The diesel engine compresses only a charge of air and ignition is done by the heat of compression. |
| 4. | Compression ratio is low. | Compression ratio is higher in diesel engine. |
| 5. | Less power is produced due to lower compression ratio. | Due to higher compression ratio more power is produced. |
| 6. | Petrol engine is fitted with a spark plug | It is fitted with a fuel injector. |
| 7. | Burns fuel that has high volatility. | Burns fuel that has low volatility. |
| 8. | They are used in light vehicles which requires less power. Eg: car, jeep, motorcycle, scooters etc. | They are used in heavy vehicles which require high power. Eg: bushes, trucks, locomotive etc. |
| 9. | Fuel consumption in petrol engine is high. | Fuel consumption in diesel engine is less. |
| 10. | Lighter | Heavier |
| 11. | Petrol engine requires frequent overhauling. | Overhauling of diesel engine is done after a long time. |
| 12. | Lesser starting problem. | Greater starting problem. |
| 13. | Lower initial cost. | Higher initial cost. |
| 14. | Lower maintenance cost. | Higher maintenance cost. |


A turbine is a device that is capable of absorbing energy from a given fluid stream and converting it to useful work. A turbine consists of a shaft or an axel which can be rotated around its own central cylindrical axis and blades attached to it. The blades of a turbine have the shape of the blades of a fan. An incoming fluid stream causes the axel to turn.



There are two major methods used to classify valves. These include method of control and valve function. Most valves fall into one or more of the classifications listed below. It is important to understand how the valve operates, as well as how it is best used, to reduce the need for valve maintenance and extra wear on the valve parts.



The globe valve is suitable for use on a wide variety of applications, from flow rate control to open/close operation.In this type of valve, flow rate control is determined not by the size of the opening in the valve seat, but rather by the lift of the valve plug (the distance the valve plug is from the valve seat).
