When I was teaching, I liked to incorporate "one liners" into devotionals that I used at the beginning of class.
One student (Mario) returned from a trip to the East Coast and said he saw one of the "one liners" posted on a sign in a restaurant in South Carolina. It even had the reference to me on it.
Frankly, I was a bit stunned.
The "one liner" is: "WHAT YOU TOLERATE, YOU WON'T CHANGE." I don't know the original source. If you do, please post it. (I don't know who said it, originally).
