If you forget what you're about to say:
- Repeat - repeat the last part of your speech to yourself, to help you remember the rest of the speech
- Drink - slowly drink some water while you are thinking, this gives you extra time
- Drop - drop something onstage and then think about your speech while you are picking it up
- Ask - talk to the audience and get some feedback from them to take the focus off you and your speech
- Breathe - take a deep breath in, let it out, take another deep breath in, and relax, this will help your mind relax as well and make it easier to remember
