[rhelv6-list] Going from "good" to "expert"

with "current experts" anymore...)

I've been playing with Linux for roughly 12 years.  I feel I'm "good"
at it, but I lack "real advanced skills".

I've completely skipped the whole SELinux-wave.  I would have been
forced to learn it, but my co-workers and employers were too
intimidated by it, so I never bothered.  I also skipped really trying
to understand SystemTap, and that's another (perhaps) advanced skill,
that would make me truly a "one of a kind" based on what I know my
immediate co-workers know about Linux.

Anyone have any good tips/references to how to take my skills to the
next level?  I've seen a few half-decent mini-books like "Vmware
interview questions" that may seem stupid, but actually do provide a
few things that I think I need to brush up on.
