Just wanted to share a quick tip about preparing a speech or presentation, regardless of your industry.This is something that I have done, and it works every time. Using powerpoint is something that I personally abhor, as I have always felt that it detracts from the art of public speaking, and instead gives the presenter the chance to have, use, and rely on an electronic crutch. In the event that the computer or projector breaks, catches fire, etc, a person who had their entire spiel in powerpoint may find themselves completely at a loss. I suggest preparing a speech first off by writing the entire thing down, and practicing as much as possible. Once you have that firmly in your head, use powerpoint as a way to add a bit of visual flare to the speech. A slide here, a chart there, but ensure that you yourself are the focus of the presentation, and not the screen. Otherwise, the audience goes into Zombie Mode, nodding from time to time, and struggling to keep their eyes open. Move about the stage or room, and return to the computer only to change slides, if you do not have a remote. To sum up, learn and practice public speaking first, and THEN go on to enhance the speech with visual aids. All the best!
