Leave work right at quitting time, regardless of whether you're in the middle of a project -- like Fred Flintstone in the opening sequence of every episode of the Flintstones. (Shouting "Yabba dabba doo!" is optional.)

Clear paper jam? Heck with that! It's five o'clock -- time to slide down the dinosaur.
