How much of your day is taken up by mundane tasks? You know the type of tasks I'm talking about:
Those repetitive tasks which, although simple, take little bites out of your day. You could craft something custom to take care of them, but then that's another thing to maintain. Maybe you create a few cron jobs and scripts for them, turning your once amazing setup into an unmaintainable mess.
We are skilled engineers, we want to be building stuff, solving interesting problems, and getting sh*t done. Your time is too important for you to be constantly disrupted by the simple stuff. Even the smallest task will have a large impact on your time as you attempt to get back in the zone.
