Here is a comment I wrote yesterday, which might apply here as well: I think that this is not the kind of thing you learn by reading a book - or sitting in front of a computer. It's a people thing. People have a knack for seeing through other people, whether they believe what they are presenting, like what they do etc. These are the things I would recommend if you want to do a great demonstration: - Love your product - nothing shines through like enthusiasm. Don't be afraid to show it either. - Talk to people, study their reactions, smile to the waitresses, hook up with girls (or guys if that's your preference), start conversations with strangers on the bus. Like in all other walks of life if you practice interacting with people you will become good at it. - Study great speakers when they do their thing - Start by looking at some of Steve Jobs keynotes. The guy is amazing. Bill Clinton and Barack Obama are great at it too. - Be prepared - Do your presentation until your girlfriend starts complaining that you talk in your sleep and she has heard more about you product while you sleep than she has heard about her other girlfriends sexlife. And that's a lot... Steve Jobs recites until everything is absolutely pixel perfect, and every eventuality is covered - and it shows. On their keynotes I heard that they have three independent AV systems. Just in case two of them break down. - Read Dale carnegies "how to win friends and influence people - it's much better than all the modern crap. It's from the 1930's if my memory serves me correctly. Good luck :-)
