“The speaker had found the secret to managing the Soloman Brother’s class of 1985: Win the hearts and minds of the back row.”
– Michael Lewis, “Liar’s Poker”
A good sign that your presentation is succeeding is by the reaction of the people in the back row. Are they engaged and asking questions or are they passive and daydreaming? To keep them active tell stories, ask questions, and make sure your slides are clean and simple. If your audience can’t read the slide, it serves no purpose other than distraction. It’s easy to keep the front row interested, it’s when you convince those in the back row that you’ve won.
