System Administrator. No experience and how to deal with it?

Question

System administration

Tell me, give advice ... I
worked as a system administrator for 5 years, basically I didn’t do anything global, tk. had a main job, a second job with the same profile, a family and studies at the university. There was simply not enough time and energy to develop their abilities.
Due to the fact that firms have nothing to do with IT, development as such was not required, any dreary (sometimes) work, assistance to users, 1C, EDS, video surveillance, components, consumables.
I'm graduating from high school next year, but for now I want career development ...
I looked like interviews, they consistently knock me down at every interview, I can’t understand what they want from me, I know for sure that I can easily figure it out in many ways, networks for me are not wilds, I know how iron works, but they kick me every time one and the same that they didn’t hold servers, didn’t raise them, and I don’t know cisco, etc. but how can I know when I have never seen it in my eyes, I haven’t held it, I haven’t felt it ...
and it’s not only about cisco and virtual machines, I also know what and how, I raised servers, set up ... what’s the point? I won’t raise the load on my home computer, and I won’t meet regular situations with RAID arrays (I don’t have arrays at home) ...
in general, such speeches, I don’t know where to fight ... some direct hopelessness
but I can’t explain it on my fingers, they don’t believe that I can figure everything out easily, only I probably need to push me for a day or two

Answer 1

go to the support of an integrator, as a field engineer: you will very quickly gain sysadmin experience not only with ciscos, but with enterprise storage, tape libraries, etc.

Answer 2

to esteem books on tsisko, it is not difficult to make raid of the house what difficult situations can be with it that? Well, the disk broke and changed everything.

Answer 3

There will be no miracle while you are doing nonsense. It's like quitting smoking. You can talk about it forever without doing anything.
The Internet is full of courses, full of information, and only your laziness does not allow you to develop.
Admit it - you're a slacker!
Either put up with it, or start fighting with your laziness. There are no other options

Answer 4

There would be a desire, on tsiska - there are excellent virtual environments with images, at least GNS3.
Of course, it is good to know OSI, statics, vlans, dynamo, but without knowledge of the syntax, you will have to understand n times more than a specialist with experience.
For servers, storages, services and any enterprise level products of MS, *nix or any of the vendors - there are always virtual machines on which all this can be raised and studied. If you want to be a system administrator - you need to be able to configure ms server, you need to be able to raise a cluster, you need to be able to raise and configure sql, iis, esxi and other essential services (you should read the full list in the vacancy you are applying for).
With RAID - generally no difficulties should arise.
Conclusion: One of two things, you are either lazy or lying. Because before an interview for a vacancy, the list of required skills always contains the technologies that are needed for this vacancy. And if you see more than 30% of them for the first time - of course you will either not be hired, or you will not pass the probationary period.
