Finally, this week at work I felt pretty productive straight through. We got a pretty significant customer due in part to technical problems that I helped solve; I've got a feel for the older generation of hardware; and I'm beginning to feel not totally incompetent as regards the software, though there are still huge areas that I don't yet understand.
Unfortunately, I'm showing up at work at seven in the morning, which means waking up at half past five and going to sleep by ten at night. Worse, it's not terribly painful to do so anymore, and I'm worried that I might soon start enjoying it. (I think I'll like it better when it's not the dead of winter any more.)
