Day 2 of the new job is done, and I'm quite weary. Part of this is due to lack of sleep, partly having to be awake in the morning, partly the new environment, partly trying to absorb everything at once. In some ways, it's eerily reminiscent of my first days at Google, which is not terribly reassuring; more than once I've had the "Oh shit - am I really capable of doing this stuff?" reaction. Right now, it sounds like I'm more-or-less going to have to shadow the network ops guys for a while and figure out how to do their job before I can do the things I'm tasked with doing myself.
I should probably find another shrink sooner rather than later.
