LEARN 'man', 'apropos' and 'info' they are almost always there
in every system and they hold the knowledge of the OS.
Start with 'man man' and know the help system inside and out
because after 15+ years working in Unix/Linux environments
a day doesn't go by where I don't hit at least 1 man page and
knowing how to flip through it to the parts you want will
save you untold time.
Oh and don't forget virtualization is your friend in learning!
VMware workstation, Parallels, Virtual Box, Xen, Hyper-V, they're
all good for learning!
Create a VM per-distro, see how each distro installs, see how each
is managed. Take snapshots and play around with their configs, see
how they break, see if you can fix them, if not revert to the
snapshot. Get your feet wet.
