A few more notes.
As a junior engineer, I grasped from other engineers the concept of looking at the big picture, and what matters, while leaving other things for later. These are likely to change anyway, so why bother thinking of them now. Looking at a big picture means developing a design criteria for all parts of the project right at the start, such as, determining the short circuit levels (by computer) at various plant busses, allowable voltage drops, outage contingencies, big motor start, etc. Then, I develop overall key one line diagram. Once I have done that and have it on paper, I have my base and reference and talking points for everything that fits inside. It's not frozen in concrete. I can adapt it as I go along. If you do this once, you can replicate it again and again on other projects, based on the clients' requirements and new requests, capacity of production and levels of automation and security demanded.
Most employers do look for individuals who talk in terms of looking forward and grasping the whole concept of the project. One day at SNC‐Lavalin, I had a chance to see my file they made after my job interview and it read, “Impressive view of looking at big picture.”
Also, as a beginner engineer, I was once interviewed by an American company. In their books of potential candidates, next to my name was written: “Capable of looking and seeing a bigger picture. Hire him, when opportunity comes up.” I heard that little jewel from a head hunter who called me up and offered me other positions. Head hunters dig out their information from their contacts in the HR (Human Resources) of the companies they deal with. I was not born with it. I looked up to and learned it from other engineers who had impressed me.
When you do your work, share it with others. Be a team worker to be able to succeed in this type of work. There are other disciplines involved on the project and often you will find out something that will help you make a proper decision or make a modification you didn't notice before. So, be a team player. Then, when you are done with an assignment, tell your boss that you are done. He loves to hear that. If you are holding it back, soon it will be noticed. Bosses like to hold onto their best producers and keep them busy.
When you are finished with your assignment, tell your lead engineer to give you feedback. Don't be afraid of his review. Don't work in isolation. Share the ownership of your assignment with him. Involve him as you work on it. He will appreciate that. Besides, he is likely far more experienced than you are and experience is what counts in electrical engineering. He may have a different approach for certain parts. Broaden your thinking, evaluate his input and implement it if beneficial and more economical.
Always show interest. I was always curious. As a kid I wanted to be an engineer. Being a medical doctor also crossed my mind. Later on I realized that being a doctor would have been a mistake. I was not made for it. I function by logical thinking. I don't want to learn anything by heart. I learn and gain experience through logical interaction. Most of it was by observing and listening to others. Being interested puts you in front of the events. Many a time I was sent to investigate a situation about which I had not a clue. Nobody else on the project had a clue either. So, others rejected it and declined to be involved. I always went for it, tried my best and most of the time I found solutions.
Enjoy engineering. This has been your biggest investment so far. Go for it.

And many more.
Let us not forget those engineers who I have worked with and who have left significant impact on my early career.
| Andy Sturton, Shawinigan Engineering | Relay Protection, Grounding |
| Jim Erath, Shawinigan Engineering | Power System Engineering |
| Ernie Siddel, Canadian Atomic Energy | Reliability |
| Farid P. Dawalibi, Shawinigan Engineering | Grounding |
The first three I knew as experienced electrical engineers who readily shared their valuable experience on me and other young engineers. The forth one was a junior engineer just like me when we worked on some power projects. He took great interest in the grounding issues on the projects. Then he wrote the first computer program to calculate the substation grounding requirements. If one searches on the net anything to do with grounding, his name will appear as one of the greatest authorities in this area, including on so many IEEE papers.
About the Author
Zark Bedalov explains that as a kid he was always intrigued by electricity. He would turn a light switch on and off for hours and observed the light to come on. If the switch sparked, that intrigued him even more. There was no one there to explain to him what was going on in the wires. In his early school days, he was punished for smashing a capacitor to pieces for trying to see what was inside. A lot of greasy paper was inside.
He graduated at University of Electrical Engineering, Zagreb, Croatia, in 1965. Also, attended some master degree studies at the University of Toronto.
His first job was in a factory for power transformers. Soon he realized that making a transformer is 90% mechanical and
