When I worked on a book called Adapt, I became very interested in feedback. I’m very conscious of how rarely we get good feedback.
And I am aware that I rarely get good feedback as a speaker. You step offstage, and you say to people, “How was that? Was it any good?” And people say, “Yeah, it was great.” Of course, they say it was great because it’s difficult to get onstage and give a talk, and no one’s going to say, “Actually, you sucked.” You don’t get any good feedback. So I’ve taken to saying to people, “Can you think of one thing that you would recommend I do differently next time?”
