In 10th grade I joined the debate team. The 1976-77 National Forensic (法医的) League debate topic, used by high schools everywhere. (29)Just reading the topic again makes me sick with remembered dread. You had to get up in front of a judge and present a response to the other team’s proposal, which you’d just listened to for the first time and for eight solid minutes. You had five minutes to prepare, 480 painful seconds to respond. But over time I decided I wanted to win. And to win I have to convince the judge, to move him or her somehow. And then it became fun.

How will you do if you want to be a good speaker? Memorize your speech. That’s right. Memorize every word of it. Deliver it in front of a mirror five times, six times, ten times.

The slides are for your audience, not for you.
