Question about Information Technology jobs?

I earned a Masters Degree in Computer Science in 1989 and I worked as a System Administrator on OpenVMS systems until 2002. I have not worked full time since 2002. I have had several part time jobs and I am employed part time at a convenience store - I make coffee, clean, etc. But I have not worked... show more I earned a Masters Degree in Computer Science in 1989 and I worked as a System Administrator on OpenVMS systems until 2002. I have not worked full time since 2002. I have had several part time jobs and I am employed part time at a convenience store - I make coffee, clean, etc. But I have not worked professionally in Information Technology since 2002. Obviously, my skills are extremely outdated. I would like to know if I were to try to update my skills, what skills should I learn? I was a fairly high level administrator, but nobody uses OpenVMS anymore (except a few places) I guess I would like to know what kinds of skills I could learn to become employed again. I know I don't have much of a chance because too many years have past, but it doesn't hurt to try - right? Things have changed so much, I don't even know where to begin. I was a hardware / systems person rather than a programmer, but I was fairly good at Oracle, etc. I feel that there's really not much of a chance of ever getting back on my feet again but I want to try anyway.
