How to prepare for a public speaking? I need to give a presentation to the board of directors. I'm very shy and I need something to give me confidence, because I cann't screw up with this presentation and at the same time I know that when I get very nervous, I start to stutter.

First, you need to write the text of your future speech. Then you can rehearse it and this will help you be a little more confident when it comes time to speak in public. I think that writing a good speech is not very difficult, but you may need advice and recommendations from professionals, for example, in this article  https://wr1ter.com/informative-speech , it ' well written about informative speech definition. It seems to me that you can find more information on such portals before you start writing your text of your speech.

I didn't expect such a quick and helpful answer. Thank you for sharing this portal. I have already found several articles on the topic I need. It really helps me in writing this college assignment, thanks.
