Unnecessary work includes the tasks that are both unproductive and unattractive—like rearranging the papers on your desk or the files on your computer.

Spending time on unnecessary work tasks keeps us busy, but such busyness is just an active form of laziness when it doesn’t lead to actually accomplishing anything.
