Picture this — it’s Monday morning and you have to give a major presentation to the rest of the office. You spend hours in front of the computer researching statistics and jotting down ideas onto a stack of notecards. As you move through each point of your presentation, you notice the attention of a worker has wandered to the bird outside the window. Another fiddles with the pen on his desk. You wonder how anyone could think about anything else when you are giving such an interesting, original and well-researched presentation.
