Public Speaking

I am taking a 6-week mini-course on public speaking, in hopes to lesson my nausea every time before I have to give a workshop.

I need to come up with an idea to give a speech in the class. Next week I have to have prepared a 5 minute introduction. I have no idea what to speak about. It's way to open of an assignment for me!

Hey Hindu -- any ideas? This is your thing!

Anybody?
