From Seth Godin:
1. You believe that you are being actively judged
2. You believe that the subject of the talk is you
When you stand up to give a speech, there’s a temptation to believe that the audience is actually interested in you. This just isn’t true. (Or if it is, it doesn’t benefit you to think that it is).
You are not being judged, the value of what you are bringing to the audience is being judged. The topic of the talk isn’t you, the topic of the talk is the audience, and specifically, how they can use your experience and knowledge to achieve their objectives.
The members of the audience are interested in themselves. The audience wants to know what they can use, what they can learn, or at the very least, how they can be entertained. If you realize that you have a chance to be generous in this moment, to teach and to lead, you can leave the self-doubt behind and speak a truth that the audience needs to hear. When you bring that to people who need it, your fear pales in comparison.
