Thanks for the shout-out, Cam! Yes, I wrote a book on how to become a great speaker, called From Presentation to Standing Ovation. You can check it out on Amazon.

And if you're interested in immediate how-to tips on public speaking and confidence, check out my interview on the podcast Superhuman Entrepreneur.
