Knowledge at Wharton - Interesting Article on Customer Behavior

From a the latest Knowledge @ Wharton newletter, I came across an interesting article entitled "Beware the Walking Dead: Analyzing Customer Data from a Multi-Service Firm." Click the link to read the article. The article speaks to the importance of leaving alone your customers who are about to discontinue using your services. For businesses that offer multi-services (from financial institutions, to telecommunications providers...and yes, I do think photographers are both customers of and, in some cases, vendors or providers of multi-services).

Advertising - Two Short but Important Quotes

Twenty years ago while pursuing my undergraduate degree in Marketing / Advertising at Missouri State University, I had an extremely bright professor named Dr. Steven Greene for my Principles of Advertising class. If I remember anything from his class (one of my best), it's these two very important quotes:

"Zig when others zag."

"Creativity is measured at the cash register."

If you have any short, but powerful quotes that have taught you a lot about business...feel free to post them in the comments section.
