Starting over, making a living with linux?

I really like to use linux, although I freely admit I don't know squat about it. I can install it, update it and get it to most of what I would like it to do, up to running some windows apps on it.

I am going back so to school starting on the 25th, with a declared major of Information Technology. I am however not convinced its what I would like to do for the rest of my life. I really enjoy most everything about the computer information world, except macs =D

Anyway basically what I am asking is what would you do if you could start over and do it again?

Is there a good living in Linux? What would you study? What direction would you go and why?

I'd like to get all the info I can before I get to far into my degree that turning back would be a bad idea.

I wont be looking for a job for quite some time. I've got to finish school first.

Just an idea of where to go with my education.
