I will never forget the time about 23 years ago when I showed up for a sales meeting, and was planning to give a demonstration of the software I was selling to the CIO of Daiwa Securities of America in the World Financial Center, downtown New York City. It took me weeks to finally set up the meeting, and on the day of the meeting everything seemed so perfect. The sun was out. It was warm. I had rehearsed the demo with my SE to the point that I had it memorized word for word. What could possibly go wrong? Plenty, I found out!
