Patrick Winston's "How to Speak": an hour well spent (2018)
An MIT tradition for over 40 years. Winston opens with an "empowerment promise" (what you'll know at the end that you didn't at the start) rather than a joke, then covers time and place, boards versus slides, informing versus persuading, and how to stop. His argument is that communication quality comes mostly from knowledge and practice, with talent a small factor. Your notes are where the knowledge lives; a talk forces you to choose a single order for it.
Where I'm less sure: these are heuristics from one gifted lecturer, aimed mainly at academic settings like job talks and oral exams. His ranking of speaking above writing and ideas is an assertion, not a finding, and some of the slide advice reflects lecture halls more than video calls.
Question: When you turn notes into a talk or presentation, where does it usually go wrong for you?
