Identify your audience and talk only about things that matter to them. Focus on what’s important to them, not to you. As you are creating the material, keep putting yourself in the audience’s shoes. It takes discipline but keep stepping back and looking at it from their perspective. If you have point that the audience is not going to care about — skip it. Then pay attention to the audience in real time. If you feel you are not connecting well, establish some direct interaction to change that. See what is resonating, and spend more time on topics that are peaking their interest, rather being tied to your original planned presentation.
