I’ve been making speeches and talking on radio and television for more than 30 years. And I can tell you that public speaking is not a “gift” like musical talent．_ 67  . Here are some of the lessons I have learned:
Your audience is going to come away with one or two of your main ideas．One or two．Not tenor 20．  68 ．And if you don't have a clear idea of what you want to say, there's no way your audience will．  69  —how you are going to open, what major points you want to make and how you're going to close．
When I do a radio or TV piece, I often write the last sentence first．___70___．A strong close is critical; the last thing you say is what your audience will most likely remember．
