I always chuckle when someone tells me that I seem very comfortable with public speaking. The reality is that speaking to an audience gives me nerves EVERY. SINGLE. TIME.
I fret for days beforehand, worrying about what the heck I will say. I rearrange my slides a billion times, fussing incessantly over silly formatting issues. The day before, I find myself thinking up bizarre excuses to get out of the speaking gig altogether. And the night before? I can forget about getting any sleep. I am a giant basket case, no matter how many times I present.
Thankfully, I have some tried-and-true conference speaking tips that help me manage the anxiety, giving the aurora of confidence even when I am a trembling mess of anxiety!
