Instead of obsessing over exactly what you are going to say in your speech, you should read more on the subject you are going to present or on similar subjects. Even if you’re a guru in the matter you’re speaking about, getting the latest news or refreshing your perspective can only help.
The purpose of doing this isn’t getting more information to cram into your presentation. The purpose is focusing your mind on the subject. When you interact with new knowledge, new brain pathways are established and old one are strengthened. Reading on topics related to your speech gives you a sense of perspective and warms your mind into being eager, quick, curious and open.
As I have said before, a speech isn’t only about the information you’re disseminating. It’s also about your attitude, your state of mind and your enthusiasm. By setting your mind to “work” in a specific area of information, you will instinctively find that topic more interesting and more share-worthy. Moreover, you will gain more confidence in your ability to bring new information to others.
Imagine this (random example): one morning, on the subway, you find some sort of breaking news about a big company merger that will impact the economy of your country. When you get to the office and have your morning coffee with your co-workers, you’ll be keen to spread the word. You’ll feel like you have something important to say. You’ll explain in great detail and in an intriguing fashion the piece of news and its implications. Why ? Because your mind genuinely believes the information you have recently acquired is of the utmost importance for you and everyone else.
Now let’s imagine the opposite: if you would use only year-old pieces of information in your presentation, it would be boring to you. You already know all that stuff for six months now ! This makes you subconsciously assume that so did everyone else. One way or another, you project your state of mind onto the audience. Therefore, you first want to make your presentation exciting for yourself. Because even if it’s a revolutionary super-string theory or some great new technology, if it’s boring you, you’ll think it’s boring to them and you’ll make it sound boring.
Getting new information or news views on a subject you’re already familiar with will boost your confidence and enthusiasm. Those are exactly the features you want in your speech. So always broaden your perspective before each presentation and spice it up with information that is new to you.
