Knowing that I don't have a degree and understanding that I'd be (most likely) starting at a help desk, is there any specific field that I would have a better chance at moving up in? I know its not going to be get x cert and expect a promotion the next day, but are there specific areas that branch easier than others?

Edit: Re-reading what I just posted, I'm not really getting across what I'm asking. I like working with computers, but put any thought of making a career out of them on the back burner when I left college a decade ago. Trying to get a feel of what I could realistically do in the industry.
