What is the difference between a con artist and an entrepreneur?--NCIS Quote and Beyond

In the Television series “NCIS” Season 12, Episode 17: The Artful Dodger (2015), there is a father and son conversation between Anthony Dinozzo Sr. (Robert Wagner) and Anthony Dinozzo Jr. (Michael Weatherly).

“The difference between an entrepreneur and a con artist is that an entrepreneur believed in the dreams he’s selling. Whether my deals fell through or not, I believed in what I was selling.”

Con Artist and Scam are thrown around far more than necessary in referring to different types of business. Entrepreneurs and Salespeople have always been vital to economic growth and progress throughout history. This quote from television is an insightful prompt to start conversations with those who maybe be skeptical or cynical.
