Sometime maintenance eats from our creative and developing time and when there is a Production issue, nothing else matters (Metallica: Nothing Else Matters). As compared to you I've started my work day lazily (working from home allows that), but I recouped that in the afternoon when my hunger to write automation tests in Java got me. And while I had few failures, I succeeded to run some successful tests. Time to close the day on a positive note, so I've stopped.
