“Dan, I came to a stark realization in one of your classes a few weeks ago. I realized that no matter how long we may have been doing the jobs we have and how old or young we may be, we can still learn and refresh our approaches to how we relate to our customers… The thing that struck me the most was the number of opportunities we have to influence others. Without your class, I would have never known that I have personally squandered many chances to influence people to my advantage.
