My public speeches

Actually, more like hall of shame because I cannot watch/listen to myself without cringe, but in this time and age everyone has to be a salesman. Well, not really, but it kind of help with self-development and getting confidence, so whatever. Remember kids! You don't have to be competent to be a public speaker! (Or write a book. Or blog. Or OSS. Or get a job.)
