I actually should not do this today. I should not spill this secret. But I want to share with you the secret of my trade and my business using which you can get the most out of public speaking.
My Board of Directors is going to be upset with me for giving away trade secrets but who cares. Here is the secret: if you are taking a class on public speaking and want to make the most of it, here is what you have to do. Think of a few topics of interest that you want to present to your class, practice it on video in your cellphone, see what you like and dislike, and try to reduce your flaws. Go into that class knowing that you are doing the best that you can.
In this way, your teacher can focus on helping you to hone the finer aspects of your skills. They do not have to waste time on data dumps and pointers. You need to become comfortable in using your equipment to record videos of yourself.
