One of the greatest thrills you can have as a professional speaker is addressing a sold-out stadium packed with 10,000 people. In 40-minutes you can reach more people with your message than most speakers reach in years. I’ve been lucky enough to give lots of stadium speeches, and I’ve learned some important lessons along the way. Speaking in a stadium is different than speaking to 100, 500, or even 1,0oo people. There are many more variables to consider and far more things that can go wrong.
