Presenting in front of 3000+ people (including Robert Herjavec) at the Startup World Cup finals - piece of cake. Just kidding - my heart was thumping hard and pretty sure my legs were shivering at a high tuning frequency and the chemicals responsible for triggering my stage fright had full thrusters on. Thankfully no one else could sense it and I received tremendous and support from so many people after. Maybe I'm starting to finally enjoy public speaking.
