There is a saying in the Linux World RTFM which stands for Read The F*****g Manual. Alot of times the Manual is way above the reader. Being from the Windows were everything is done for you and even though Windows is as faulty as it is, not having a computer to run Linux when Linux first came out but today Linux will run on just about anything.
As you grow into your world of Linux one of the things I notice is how much easier it is to read the manuals. How much easier it is to find information on the web. How much easier it is period.
Some one once told me it takes about two years to get to know your system. That is just about where I am now.
