In The Last Lecture, what was the author's mood while giving his presentation?
Randy's positive mood is reflective of his lecture's topic.
Randy knew that people might perceive his "last lecture" as focusing on death and dying. However, Randy challenged this preconception through his choice of topic. Randy decided to make the lecture about dreams and the power of transformative hope:
Sitting there, I knew that despite the cancer, I truly believed I was a lucky man because I had lived out these dreams. And I had lived out my dreams, in great measure, because of things I was taught by all sorts of extraordinary people along the way. If I was able to tell my story with the passion I felt, my lecture might help others find a path to fulfilling their own dreams.
Randy's last lecture is not about his passing. Rather, he seized it as an opportunity to talk about the beauty of dreams.
This topic contributed to Randy's very upbeat mood. Randy was convinced that his entire life was a testament to dreams being realized. It is for this reason he apologizes to the audience for not being "as depressed or morose as I should be." Randy feels that the arc of his life has been a glorious one because he accomplished meaningful dreams. As a result, his mood while giving the lecture is positive.
