I want to thank you, again, for your presentation.  I’ve attended many, many, professional presentations over the years, and yours was one of the best I’ve seen.  Both the style of presenting and — most important — the content were fabulous.  And your point about change and lack of predictability resonate with me, because I’ve been preaching to my students for years that advertising is all about change, and they should not only get comfortable with it, but should embrace it.
