Then, I open up those slides and start editing. Perhaps one of the most important things about working on presentations was quoted in Garr Reynold's presentation at the top -- that to put together a really good presentation that you must get OFF THE GRID. Disconnect. Think. Challenge yourself.
Often the best content for presentations is written in my journal in the mornings when I allow myself no technology and a couple of good smelling candles, my Bible, Bible Study book, and journal. (perhaps the most important connection of my day.)
Sometimes I write them on airplanes after my battery has died - and those are often very good. I always WRITE first and THEN go into powerpoint. I would not say I've arrived, but that I've come further than I was and am moving ahead to become better than I am now.
