The beginning of understanding is the acknowledgment of ignorance.
I think Socrates is credited with saying something similar....
So true is this statement, We as humans tend to be our worst enemy when it comes to learning, we all want to be accepted by our peers and feel that we are an important part of the chain, no one who takes their work seriously wants to be left behind because of lack of knowledge or hear the words that we don't know what were doing but many times we do just that, we block our selves from learning new things by thinking we already know everything when in reality we don't have a full understanding of it.
When we can open our minds and realize there is no one on this planet that has a full understanding of everything then we can open our minds to learn new ideas.
I have found over the years that those who love the job that their doing tend to take the time to better learn it and are not as lazy to take the time to learn it to its fullest as it becomes less of being a chore if you love what you are doing, we don't mind when we run into a problem we don't understand as we will do the home work to find the reason of what we are missing, because we know it will only make us better at what we are doing.
You must ask yourself, are you a career electrician and want to keep learning your job to be the best that you can be, or is it just another job and you only want to just get by with only learning as much as you need to.
I have also notice that career electricians tend to have a greater self pride in their work and don't take short cuts even when no one is looking, we tend to put quality ahead of quantity, and it can pay off in the long run when we get called to do jobs because a knowledgeable customer knows it will be done right and will be safe and even will pay a higher price for this type of work, sure not all customers don't think like this, but I would rather do work for customers who do, as smarter customers can be longer lasting, and are more likely to give you more work over time because they wont be price shopping because they want the job to be done right, Do you take your car to a repair shop just because it is the cheapest or do you try to find out if they know what their doing and can make the repairs correctly, I hope the latter.
39 years in this field and there is so much I still have to learn, Now I'm now studying more about VFD's, AC to DC drives, and PLC's as while I have installed a few over the years, I never had to work on them on any regular basses, but now working in the steel industry, it's a big part of my job so I want to know them to the fullest, not just how to install one, but why each parameter is set to a specific setting so when problems comes up I can make the right choices to correctly make the right changes to keep things working and production going.
