This is from an email that I want to frame and put above the mantle:

“I am the president of a power tool company. I read your book on Monday on a flight from Charlotte, NC to San Jose, CA. I had a customer meeting on Tuesday and had to completely change my pitch. Instead of our typical power point telling the customer how much better our tools are, I decided to be “concrete”. I disassembled our power drill and a competitor’s drill right in the middle of the meeting to show the customer how our product stacks up to competition. They loved it.”
