"Work smart not hard" is a classic saying, and its applicability to real life situations is timeless.
And it's been around since well before just within this current century:
"The Origin of “Work Smarter, Not Harder”
The phrase “work smarter, not harder” was coined in the 1930s by Allan H. Mogensen, an industrial engineer who created the Work Simplification Program - a methodology designed to help people produce more with less effort, which he explained in his 1932 book Common Sense Applied to Motion and Time Study.”
He was also noted for polularizing flow charts...smart guy!

Anyway, no one suggested to put YT on a resume as a credential or certification. DUH. If you can't figure out how to leverage whatever you learn into padding your resume, then you're (again, applying a classic saying to a current situation) "working hard, not smart."
You can learn skills on your own, then use them to improve work tasks, which can then be mentioned and described on your resume in how you used those skills to: save the company money, increase sales, drive deliverables, create more efficient/streamlined processes, etc.
Hey, here's a quote from Mr. Mogensen, which could apply to how you're being within this very thread!
"First of all, we resist anything that is new; secondly, we all resent criticism."
Clearly, not everyone is naturally (or maybe even capable of being at all) innovative, independent, creative, or open to suggestions to new ways of doing things.
You may very well be such a person.
Is that our problem?
No.
It's yours.
Best of luck navigating through whatever comes your way next!
