Be sincere, be brief, be seated If you haven't struck oil in the first three minutes, stop boring! Make sure you have finished speaking before your audience has finished listening Your speech need not be eternal to be immortal Talk is cheap because the supply always exceeds the demand. First law of public speaking: Nice guys finish fast. When all is said and done, there's a lot more said than done. Because a woman's vocal cords are shorter than a man's, she can actually speak with less effort than he can. Shorter vocal cords not only cause a woman's voice to be more highly pitched, but also require less air to become agitated, making it possible for her to talk more with less energy expended.
