I realize this is more nitty gritty craftsmanship, but can you talk about the thinking behind the slides you used and when it made sense to use a slide to emphasize a point? Or not to?

I love powerful visuals and to me the most powerful are photographs. The one almost everyone talked about after was this one of my future wife that I took when I was a lovesick 19-year-old who was trying desperately to not to let my crush on her show. I didn't expect that image to be The One.

We had both been hired as summer camp counselors, but I had just failed at college and she had just graduated. I thought that put her out of my league and a secret crush was the most I could hope for. Later in the talk I had a line that ended "and she's sitting right there." The audience visibly warmed to that and surrounded her after.
