Some people seem to think that "busyness is next to godliness", so they make sure never to let anyone see them idle. They don't so much focus on what they are doing, just that they are doing something.
I've always taken the opposite approach. I go out of my way to make it look like I'm never busy. "Make it look easy." It's just a different sort of personality quirk.
It's fun to come across people from the other camp. We find each other very peculiar... :)
