“How to make a presentation” is among the most widely used keyword search phrases on the web because people want to learn how to present well when speaking about something in front of so many people, especially strangers. It also happens to be the subject of a great many books on just what can be done to ensure that people like what you say.
Presentation skills are not going to sprout up out of nowhere overnight, of course, especially from any book, much less any ol’ book on the topic, of which there are a large number going back thousands of years, even. However as with anything in life practice should make perfect and the secret is to really take to heart what these kinds of books have to offer.
By the same token, a professional speaker knows a lot of things which are not in these kinds of books, things that require the kind of first-hand experience that’s honed over many years or at least many attempts. You get good at something by doing it, and like any art the ability of public speaking requires not just an understanding of the theory but actual mastery of the practice.
Another way of becoming a better speaker might be, ironically enough, to try one’s hand at writing. Such an exercise frees up the soul, in time anyway, which is a necessary ingredient for successfully engaging a crowd: the ability to invest all your heart and soul in delivering a message. By the same token, writing, real writing, should engender an expansion of the mind (or “soul”) such that one’s very capacity for the recently mentioned “heart and soul” should likewise increase.
Unorthodox musings, to be sure, and perhaps not immediately practical, or ever practiceable – but it’s the truth, all the same: delivery has to do with character, in the sense of who and what one really is. Writing (and, by a further extension, reading) may help bring it all out.
