To get good sysadmin work, hang out with other sysadmins (online and off). Personal networking is where quite a lot of the decent jobs come from. IME, quality of co-workers is almost more important than what the business actually does.

This is of course not advice to hold off looking until then ;-) Six years' sysadmin experience, even at college, is very nice on the resume.

(I assume you're paying serious attention to that carpal tunnel - touchtyping properly, using a decent keyboard, trying mouse substitutes like trackballs or trackpads - the other-optimisations are endless ;-)
