I love speaking in public *about something I know a lot about.* I look for opportunities to do it! But I'm so introverted I peg the introvert-o-meter.

When I was in my 20s, I worked part time as a radio disk jockey. It's the perfect gig for an introvert with something to say: I had an audience of tens of thousands but I was alone in a dark room while I did it. It had an unexpected benefit in that it taught me to speak without a script, and to speak as though I'm talking only to you even though you're in a crowd.
