Later on you have a lib of books. I have CISCO books, A+, Security, all my Unix, DOS, Linux, and windows books. I have several for work. Remember "knowledge is power". Learn all you can. If you also can (reading takes time, yet I always leave room to read every night) about electronics, phones, etc. Besides the use of phreaking and hacking, it isn't always about that. I find this stuff interesting. That is why I work in the IT field and I enjoy learning more and more. Have a good night.
