Right now, man stay outta this industry. Its TOUGH. Of course, if you want a degree before comin in, this is the perfect time. Start with getting a degree. I dont think certifications are all that good anymore, because your starting to get alot of paper techies. Once their on the job, they usually dont know what their doin....So, I wouldnt just get an IT job right now. But! I would start to make my moves on getting an IT job, such as maybe looking to get a degree (even an Associates), buying some good entry level books, get a PC (which you obviously have!). And read read read! Decide what you want to do! Are you wanting more WAN? or LAN? WAN, well, you dont need to know jack about a pc. LAN? You better know a server like the back of your hand. Administrative? A good overall understanding of the technology is good, without focusing on any one part. Keep in mind, you will never understand EVERYTHING about IT, so decide where y9ou want to focus. But! If I had to recommend one thing to learn, a keystone if you will, it would be Cisco equipment. You simply dont know how many people use Cisco. It allows you to go either WAN or LAN, since everyone from MAJOR telecomm companies to mom and pop shops use it.
Hope that helps!
