The only person who can improve your skills as a presenter and public speaker is you. Folks like me can share insights and ideas about the tools and methods that distinguish the very best presenters, but it’s you who must do the work. Just like I can sell you the tools to grow the best garden or build the best home, how you put the tools to work is up to you.
Okay, now can you ride a bicycle? Play a musical instrument? Did you learn to do such things from a seminar? By reading a book (or a blog)? I bet you didn’t learn to drive a car by sitting in a classroom.
Public speaking is the same. It’s an acquired skill. We can talk about rules and structure, but the only way you can learn to do it (and do it well) is by doing it.
Like learning to play a musical instrument, or driving, or tennis or golf, the more you do it, the more mistakes you make, the more you improve over time.
Don’t be afraid to make the mistakes. Don’t be afraid to learn from them, either.
