How to build a great presentation

Tell the audience what you plan to tell them 
Keep the audience awake while you pack their brain full of the material you promised - laughter helps keep people engaged 
At the end, summarize what you have learned 
Take a step back from your presentation, ask yourself the question, “If I was going to this session, what would I be expecting to leave with?“  Now ask yourself the question, did the presentation satisfy that need? 
When you are reviewing your slides, think, what is the audience going to call B.S. on me for?  Make sure you are making strong arguments if you are making a claim that is hard to believe.  Otherwise, change your tone. 
Then, once the flow of the presentation is solid, go back and remove all unnecessary wording, in fact cut all content from each slide, put it into the notes, and re-write the slide with only the highlighted words.  Remember in college when you highlighted the important key words.  Make your points, sweet, short, and concrete.  You want your audience listening to you, not reading 
Don't use more than 6 bullets on a slide. 
And finally, make friends with someone who is color blind, and give them your presentation.
