I just found this on youtube and I really like the ideas and the way they get their message across. I completely agree with their main idea that a presentation is all about the story. This is the first thing you need to do when preparing a new presentation. The storyline I like to follow works like the pyramid principle. Never focus on topics as a storyline, focus rather on conclusions, ideally no more than 3 and give a logical reasoning how you got to these conclusions!
