The weekend before a TED conference, each speaker rehearses their talk in the TED theater. It’s a chance for the speakers to get to know the space, for our curators to give last-minute suggestions on talk content, and for our speaker coaches to give the advice to help each speaker feel their absolute best on the day of their talk. During this time, I overheard speaker coaches Gina Barnett, Michael Weitz, and Abigail Tenenbaum give a few extraordinarily helpful public speaking tips that I’d never heard before.
