I am self taught, well sort of. I bought book after book and studied my but off. Then I started asking a ton of questions on various forums. After banging my head of the desk a million times. (just kidding

) It finally started to sink in. I bet I reformatted my first server 30+ times. You cant be afraid to mess something up. And if you do try and figure out what went wrong. Another good thing to remember if your server is giving you a error. There is a 999% chance that if you google the error your going to find a answer. If feel with all of the information available on line their really is no need to pay for a Linux coarse. Anything you want or need to know can be found out on the Internet.
