By-Two Kaapi in an oilfield

Next morning, as I sat in the front row waiting for my turn on the stage, the full weight of the event hit me. There were several thousand people in the room, and approximately 50,000 watching the webcast. It was the very definition of pressure. Steve started the segment that preceded mine, and my heart started pounding. I felt those hundred thousand eyes all about to be focused on me and feared I would crumble. I had done a bit of public speaking before, but nothing like this.

The assistant producer came over to me to guide me to the stairs at the side of the stage. I stood in the dark, watching Steve put up the slide that introduced me. Just then a wonderful thought hit me; in five minutes the whole thing would be over. If I could only keep going for five minutes I would be fine. I bounced up the stairs and on to the stage, and everything was suddenly OK. The demo worked perfectly, the audience seemed to love the product, and their applause was an incredible adrenaline rush.
