Ten million people watched MIT professor Patrick Winston teach "How to Speak" once in 2018. He's dead. Executive coaches charge $15k per session to teach a fraction of what he gave away free. His entire framework: do not read, be in the image, keep images simple, eliminate clutter, start with empathy, end with a punchline, never open with a joke, never end with "thank you." "Your success in life will be determined largely by your ability to speak, your ability to write, and the quality of your ideas. In that order." Founders drop $80k on an MBA then hire a communications coach for the same material. Engineers lose promotions to people who watched this on the train. The napkin is free. Implementing it in your next meeting is the actual edge.
