The perception of average is completely skewed by the internet. By definition, half are above average, half below. But the perception of above is judged by Ted Talks and the like. So someone that is an above average presenter is perceived as a bumbling dipshit.

So having said THAT I have a quote from a Ted Talk by Brene Brown.

If you are not in the arena getting your ass kicked I really am not interested in your feedback

For me, it's all about my perception of my self and how I did. She also said something like

Don't try to win over the haters. You are not the jackass whisperer.

Showing up is important. Showing out is important. Consistency and effort are absolutely essential.
