Thank you so much for this article, it’s really helpful. I have been studying public presentation techniques for a very long time, I understand the principles, I know what the balance between presentability and emotion should be. But I can't do it in any way due to excessive excitement and fear. I have practiced many times already, but I am still very nervous and literally shaking when it comes to presentations and public speaking. Could you please give me some advice what i need to do, how to overcome this problem?
