You are learning the exact same way we all did - by making mistakes and
learning, slowly and painfully, to correct them. I had the advantage of
teaching computer tech to post secondary students. If a mistake could be
made they would make it! From time to time a student would come to me and
ask for a "system disk" because that was what it asked for on the screen.
Of course that was just geek code for "you don't have an operating system
installed". My other favourite is when they asked "who is General Failure
and why is he reading my hard disk?".

Anyway, keep up the good work. The only advantage most of us have over you
is that we've been making our mistakes for a few years longer and hence
know a tiny bit more. As one of my net admin colleagues (who was a genius
as far as I was concerned) said: "nobody knows it all". My standard advice
to students was: the most important networking you do is not with computers
it's with people. The problems you are unable to solve today may have been
overcome by one of your friends in the trade yesterday. As another tech
told me: everything I know is yours.
