Presenting Off the Cuff
You haven't prepared a presentation but, all of a sudden, you're called upon to do so.
Begin thinking about 2 things:
a) Your Objective: what do you want to accomplish with this impromptu
b) A Structure: what will be the beginning, middle and end?
It's good to think, on a general basis, about what you're doing with these two issues in mind. Ask yourself: If I was suddenly asked to sell what I'm doing, what would I say?
And here's another exercise that will build speaking muscles.
Open a book and choose a word at random. Then start talking for 60 seconds on that topic. The more you do it, the easier it will be.
