Before you go through the whole deck and rearrange your slides and logos and fonts and made sure everything is perfect, I need you to do one thing for me: look at the whole thing and ask yourself if it contains at least one new idea? If you cannot say yes to that question, can you at least say yes to this question: does it contain at least one new perspective or way through which to look at an old idea?
If you really want to stand out as a speaker, you need to have an affirmative answer to at least one of those questions.
Giving too many presentations can instill a sense of you giving the same information again and again to your audience and going through the motions and treating your audience as if neither of them or you want to be there at that instant.
I understand that there will be times when you have to go through some perfunctory information but even then you must take the opportunity to put a spotlight on one interesting idea and you want to train people to whom you speak, whether it is your employees, customers, or clients, you want to train them into thinking that you are someone who always gives them at least one great and useful idea.
That way, you can really burnish your reputation as an effective speaker.
