Presentation practice five days before the performance

After finishing making slides for a presentation, we will practice many time. I write a manuscript before a practice, whereas I usually don't use it. I should remember the words when I write a manuscript. I exhibit a slide-show with speaking while keeping the manuscript. When I cannot speak fluently, I use the manuscript. I repeat this step. When I feel something difficult to say, it means that the word written on slide is not suitable for reading. Then I replace the word to other suitable one. I should delete any insufficient word on the slide, e.g., two phrases having similar meaning on a slide. By performing such procedure, I can shorten the slide as much as possible. The short, simple slide is preferred by all people of the world.
