The Wall Street Journal (Jan 12, page A13) listed “Do and Don’t” entrepreneurial lessons from the movies. For example, lessons from “The Founder” in which Michael Keaton plays McDonald’s founder Ray Kroc: Do recognize a concept ready to explode.

Kroc hounds nearly everyone he meets at social occasions to sign up as a franchisee or investor.
