One of the simple ways that I try to make experimentation an everyday activity is to always try at least one new thing each time I give a presentation. One such recent experiment I called “choose your own presentation.” I looked back at the 20 or so talks that I’d given this past year, and I tried to group material into the questions that I most commonly get asked. I ended up with 31 questions. My colleagues circulated the list before my presentation, and I went through the eight questions that garnered the most interest.
