Do you know if OP has certifications or experience?

Lol

Are you sure you've read the OP?

I personally would much prefer to be introduced to a new subject (like BASH101) by someone who has zero certifications but some experience and a real ability to teach.

Because I have seen a lot of super certified teachers who ends up unable to teach anything and who are recycling the same course without any practical experience in the last decade.

I don't disagree with that, but again I think you're in a wrong post. Op never said that they're so experienced but just lack certifications. What I've understood is that OP is just a power user with no other experience, neither from a job, nor from personal hobbies but on production live environments

And that being said, please explain me how you end up making such assumptions about OP's skills and what did they say that made you feel that you know about their level of knowledge.

I don't get how one can get to teaching without provable certifications or experience. I mean who will hire Joe from his basement just because he claims he's "good at Linux". Unless you're talking for something else. Like him preparing a whole course in an online platform that will give it free in order to get some traction and hoping that this will attract customers

Isn't every reinstall an opportunity for changes?
