There is more than one way to give a good speech: there is lots to say, there are lots of people who talk and lots of people who listen. This eclectic mix makes it impossible to set out a specific structure for every occasion. In fact, when an audience notices that a speech feels contrived, they feel manipulated and lose interest almost immediately. The only thing that really matters is that you choose an interesting subject and present it as authentically as possible. The best way to make an impression on people these days is not to leave something written, but to spread your words and your passion everywhere, and the internet can help you do this at the speed of light. To do this in the best possible way, you can learn to improve your “communicative competence”, or to put it more poetically, you can learn the art of rhetoric.
