KLT. I suggest that if you want to do reviews, create outlines on each subject so that you can be succinct and still include what you want to say. It will streamline your work. I was in a classroom teacher. Outlines help cover everything to said without reading from a script.
I appreciate your advice but I'm very aware of my inability to speak extemporaneously. Public speaking has never been something that I have had any ability to do. Unfortunately, I have read an enormous amount of books in my lifetime and wanted to share it with others but I have only myself to do the speaking. Believe me, if I could think of a way to have someone else speak for me I would have. So I do the best I can and any viewers who don't like my presentation are certainly welcome to not watch.
I suppose you're correct up to a point but I think I, sometimes, can get the gist of what the books are saying but I really don't understand it. Especially some of the paradoxes they talk about.
