Last spring I presented half of my Conference Communication Keynote Sandwich for YPO: Young President's Organization. It was a lean conference, and I attended the entire session, making notes of the kinds of conversations people were having and the kinds of questions they were asking. I summarized my findings in my closing keynote, which addressed the likely challenges the attendees were likely to experience when they went back to their companies with their new understandings and ideas. I gave lots of phrases, techniques and practical suggestions.
One attendee emailed me afterwards to say that my session was the most useful since it doesn't matter how good people's ideas are if they didn't know how to talk about them.
