In the program there is a core philosophy of keeping one's own side of the street clean. Chop wood, carry water, basically. Also, mind your own damn business, one might say.
Another little pithy quote they often state in the literature is that one should not "go to the hardware store for milk."
I subscribe to this website called flylady.net. She sends out daily email reminders of where you should be in her system. It's fantastic. It's based on cleaning in small spurts using a timer.

And whatever you do, don't let the s.o.b. hitch a ride.
The Scorpion and the Frog A scorpion and a frog meet on the bank of a stream and the scorpion asks the frog to carry him across on its back. The frog asks, "How do I know you won't sting me?"

The frog feels the onset of paralysis and starts to sink, knowing they both will drown, but has just enough time to gasp "Why?" Replies the scorpion: "It's my nature..."
