Here's the thing: I've watched many brilliant TED Talks. And I am sure there are many brilliant ones just waiting to be discovered. But I do not think that a TED Talk makes you a thought leader. I do not think that following a very rigid format is the best way to connect with your audience and communicate and idea that you are passionate about sharing.
One of my favorite things to do, when I’m at a conference or event, is to observe the people who are presenting. Sometimes they are referred to as “thought leaders” or “keynote speakers” or “esteemed guests”. Sometimes they are famous… or infamous. When this person is introduced - they are hyped up by the person who is hosting. There is a long list of credits, accolades, and other intimidating factors. All of this build up raises my expectations to extreme heights and I assume their presentation will knock me to the floor. This is an expert, they will inspire. Ultimately I’ll leave not only learning something new from them, but learning something new about myself. (#fitspiration, am I right?)
