The 2 qualities of a public speaker for me, first of all, is relaxation. I think this is important. Because when speaking in public, everyone gets nervous when speaking to many people, which is normal. I myself get nervous every time I speak in front of a large group of people, so you should not think that what you say is good or bad. But try to relax as much as possible. Next, I think that everyone must do this is to be themselves. In public speaking or presenting in front of many people Being yourself helps your audience believe in what you're saying and also increases your credibility
