I still get pretty nervous even though I am told it does not appear that way. I realized a few years ago that speaking on a topic you know and understand makes it a lot easier. Back in college, I would try to give a presentation on a box I didn't read or a chapter I never opened. Bad ideas and bad grades followed. When I had to give my first talk about wrestling, it was much easier and I think I got a much better grade. The moral of this story, HAVE A CLUE!
Congrats Austin
