The recipe for successful speaking

If you talk of anything you do not know, it is a matter for ridicule. If you talk about anything you have not experienced, it is reprehensible, for you are cheating your listeners. If you learn the art of public speaking and talk enchantingly using all the skills and frills recommended in the text-books or borrowed from others, it is cheating, nevertheless. Be sincere; be simple, be honest. That is the best recipe for successful speaking.
