"My biggest challenge when putting together a talk is that I want to cover too much material... Sometimes I think that my tendency to talk about too much comes from excitement--I love what I am doing so much that I want to explain it all. To be honest, though, I think when I super-size a talk it's because I am desperate for approval." -- Oh yes, this sounds too familiar. Kent Beck suggests an important exercise to deliver great talks: (1) pick one person who represents your audience (2) figure out how to grab their full attention and (3) figure out what they should do after they listen to your talk.
