I will paraphrase what one of the professional speakers says in his chapter - the goal is to not get standing ovations and speak to your audience but to speak with your audience.

One example: https://www.youtube.com/watch?v=v26CcifgEq4
In case you don't already know the secret of public speaking or storytelling or connecting with people, the secret is vulnerability.
> It takes relationships to make relationships. And, in general, to make relationships, you have to allow vulnerability. Vulnerability is the difference between a conversation that starts, "How about this weather we're having?" and a conversation that starts, "Oh my God, let me tell you about how I just fell in a puddle in front of a group of nuns." The former is so boring that it makes listeners want to crawl under a table; the latter creates a spark and a list of follow-up questions. These are two extreme examples, but generally, the more of yourself you put out there, the more others will have to connect with.
