When you practice a particular talk or presentation, you have to practice <i>handling the freeze</i>. Too many people think they have to practice just to get the sequence or even exact words right.<p>No. You practice in front of a group, as contrived as it may be, and you have them shut up, and you give your whole talk. And you get used to the feeling of icicles going through you. You learn to breath through them and get familiar with how long they last. The fact is, you are riding inside an incredible machine, and it will pump itself full of crazy chemicals when you put it on stage. You can&#x27;t let their power surprise you.<p>Edit: All that said, I&#x27;d offer my solidarity to Mr. Habib as well. I&#x27;ve certainly frozen up worse myself, and in much less high pressure settings.
