That means I tend to ramble, babble, and get off the main subject pretty frequently. It's probably hard for the audience to keep up on the rare occasions that I do speak publicly.

You know, that's actually a really common problem and is why most people are terrible public speakers, especially those who aren't shy about doing it. If there is only one thing I learned about public speaking in my years it's that to be good, you have to practice a speech constantly just so that you are more likely to stay on topic and not ramble. The practicing is to help eliminate the rambling and digressions that make speeches bad. Steve Jobs was famously great at public speaking—and he famously would take two weeks before any keynote and both practice himself for two hours everyday at work and make everyone else do the same.

Anyway, I probably tend to be more of an introvert too. I listen more than I talk and only hang out with folks I like, which probably makes me look a little anti-social by not doing the social butterfly thing and talking to people I don't like.
