And I hold 2 count’em 2 I always reread my thesis so many times that I begin to dream about if. But the day before my defense I do not at it. This give me time to let it settle and I can relax. Remember, YOU are the expert on your subject. Someone mentioned use cartoons, I did exactly that, drove home the point, and everyone remembered it. Also, someone said don’t be to technical or use too much topic/subject vernacular, this makes it tiring. I always, in teaching, speaking, strictly adhere to the . philosophy, “Keep It Simple S—–“. Unless necessary to expand, and even then Don’t Overdo It. Allow for questions, keep everyone’s interest. Leave them wanting more. Yes this is the culmination of years of work. Work you did, and no one knows you subject as well as you. Be relaxed and prepared. Enjoy this experience. Over several weeks preceding your defense date, have friends & colleagues, drill you. Also, your mentors job it to bring out the best in you, and have you prepared as much as possible. I went to a university that if had I written” my mentor was a douchebag”, in my thesis, that would have ended my doctorial pursuit, also probably have me before the ethics and the board. Be professional and present well.
