Look at them, the bugs. Humans …

Look at them, the bugs. Humans have used everything in their power to extinguish them: every kind of poison, aerial sprays, introducing and cultivating their natural predators, searching for and destroying their eggs, using genetic modification to sterilize them, burning with fire, drowning with water. Every family has bug spray, every desk has a flyswatter under it … this long war has been going on for the entire history of human civilization. But the outcome is still in doubt. The bugs have not been eliminated. They still proudly live between the heavens and the earth, and their numbers have not diminished from the time before the appearance of the humans.

Real shrewdness means not letting any …

Real shrewdness means not letting any shrewdness show. It’s not like in the movies. The truly astute don’t sit in the shadows all day striking a pose. They don’t show off that they’re using their brains. They look all carefree and innocent. Some of them are tacky and mawkish, others careless and unserious. What’s critical is not to let others think you’re a person of interest. Let them look down on you or dismiss you and they won’t feel you’re an obstacle. You’re just a broom in the corner. The pinnacle of this is to make them not notice you at all, as if you don’t exist until the moment right before they die at your hands.
