Erick, I hate to sound mean, but Saketume is right. You need to take some public speaking classes so you can learn to enunciate your words better and even out your rhythm. During this video you had a tendency to speed up and slow down, making it difficult to understand you.
This is especially difficult if you're trying to follow along with the video and the quote from Garriott on the screen. So just calm down, focus on opening your mouth wider and forming the words, and don't worry if you feel like you're going too slow. That feeling simply comes from being nervous over how much time you have left to deliver your speech. And that's easily beaten by practicing in front of a mirror with a stopwatch. ;)
