O.K. This may go without saying, but I’m going to say it anyway. Before you speak to an audience, you need to research your topic — even if you know it like the back of your hand.
Why is researching important?
Quick! Cover the back of your hand.
Now describe it in detail without looking. No peeking!
So, how did you do?
Not very well I’d venture to guess.
This illustrates my point. You need to research your topic, even if you know it well, so that the details are fresh in your mind. Public speaking does not only rely on your power of discussion or your skill in speaking clearly. You have to face the crowd with the feeling of certainty and confidence in our ability to deliver.
