I would say you should look into taking a class. I know at my old High School we used to have an A+ class. Take the OS portion if they are two different classes. Also most Comunity Colleges have classes you can take. Thats the best way, otherwise I would say, get a pos computer with 98 on it and just start f'ing around with it. Look at some of the tutorials and try installing a program like the Adobe Acrobat Demo and see if you can crack the trial part to turn it into the full version. You will learn a ton from doing that kind of crap. Macromedia is another good one because they have really good registry security.
