When you get to a plateau, think of it as a landing on the stairway to your goal. And maintenance is a lifelong plateau, so a bit of "rehearsal" for maintenance isn't the worst thing in the world.
"When one approach is not working to reach the desired goal, that's not a reason to abandon the goal. Instead, it is time to devise another approach."------Ralph Marston
"Worrying does not empty tomorrow of its troubles; it empties today of its strength."
