Okay so this is more to the new Linux people, who want to do everything more mature players can do in Linux, but have spent the time to learn these things.
Okay so what do I mean by this.
A lot of people who move to a new OS see what the older people (Intermediate Linux Users) are doing, they are doing fancy things with virtualization, kernel compiling and scripting, we talk about advanced things, and discuss things.
This to a new user is like WOW!!! but also they haven't the foggiest on what they are talking about.
Say they are talking about KSM, they are thinking WOW, this sound amazing how do I activate this? well normally it is already activated, but they look anyways.
So what I mean is this, by all means ask questions in discussions, that is what they are there for, and listen in, research the topics, but don't think that it was done over night, just take a step back, relax and enjoy linux, seriously I was the same, and that step back worked wonders, it allowed me to focus on learning things.
Now if you want to learn things faster but do not know where to look, get your self The Linux Bible, I purchased this last week, and so far its been a good read, the person who wrote it is a Linux professional, and you will learn a lot, if you want to learn extra via videos, Start with infinitelyGalactic, he does distro reviews normally, but some advice series every now and again, if you want professional videos from pros, use Linux Academy, although this is a monthly subscription, if you wish to learn Linux properly and apply it as your career, you can't go wrong.
My advice to you would be this first though, get Debian, not Ubuntu, you want something stable and something that does not break, learn how the terminal works, Nixie Pixel does some decent guides, basic stuff but it will work well.
Learn VI/VIM over nano, VI is used in the official Linux certifications, so learn that, learn how to install desktops, add repos etc etc.
Again.
It will all come in time, just work at it, and ask us questions!!
