You never know where you’ll learn about PR, marketing and branding. I had a terrific reminder this week, while re-watching the movie, “Pulp Fiction.” It’s one of my favorites, and I practically have the script memorized. Yet I never realized that its characters provide fantastic lessons on the subject of personal branding. O.K. Bear with me. I know you’re wondering how John Travolta’s comeback movie taught anything. Trust me: Quentin Tarantino is a quirky producer who wove all sorts of lessons into that gritty film.
