If I don't have a Power Point it can be quite dreadful for me. The Power Point is my security blanket. I can not practice a speech... I have a topic, do an outline, prepare my slides and print it out just in case there are problems with the CPU where I'm speaking and I go at it. If I spend hours practicing I lose focus while I'm giving a speech because I'm trying to do what I practiced, and hand gestures, the way I'm standing... yadiyadiyah it's too much. I stay focused on my outlined PPt. and I'm good to go... still nervous as hell but good to go.
