I. Principle of 10-20-30
An excellent speech PPT should not exceed 10 slides. The classic is not much essence. Similarly, the total length of a PPT speech should not exceed 20 minutes. If the time is longer, everyone will always be distracted. The font size of slides should be greater than 30, and the content should be concise and not excessive. PPT itself is used for prompting. Don't move everything to PPT, which will easily lead to the effect of watching PPT. In a limited time, convey the essence to the audience with few but precise words.
Second, summarize with the word 15.
Refine the central idea of your speech into 15 words, and repeat the summary of these 15 words in your speech, which can achieve the effect of deepening memory and emphasizing.
Third, interesting.
The speech should be entertaining. People want to see the performance of the speech, not recite the text, so that your passion can infect the audience. Of course, you should join more organizations to improve your speaking and conversation skills. These exercises will make you more confident on the stage.
