• Structure is what makes communication hang together. It's like the rails that a train runs on. Without them, things wouldn't move very far. If you only have time to do one thing in your presentation, make sure it has a clear and identifiable structure. Without this, you'll have no credibility. Once you've organized your ideas, if you step back and look at it, many times we've organized topics. We've strung together a structure with organized topics. At this point, change your topics into messages.
