Book Review: Time Management for System Administrators
Anyone who's ever had to keep a couple of hundred machines running, and a couple of hundred users from melting down, knows just how hard it is to avoid thrashing. Tom Limoncelli's book is a hard-knocks guide to avoiding or ignoring interruptions, building good habits (so that the right thing will happen even when you're frazzled), prioritization, and managing user expectations.
