Public speaking is so stressful for so many people that it is routinely used as a stress manipulation in psychological studies. Tell undergrads they have 10 minutes to prepare a speech that will be evaluated by experts, and their levels of the stress hormone cortisol shoot through the roof.

Yet success in many roles requires speaking in public. In addition to presenting in my classes, I typically give a talk per week in front of groups. People ask me if speaking gets me nervous. It does not. And I give a lot of credit to my fascination with stand-up comedy. While I’m not a comedian myself, I’ve been a fan of comedians and their process for a long time, and I think there are three lessons that anyone can learn from them about public speaking.
