What do you like about it?
Everything: I love writing bits and putting everything in the right order, I love the fact that there's a lot of psychology involved, I love that you can watch something mundane from a different angle and suddenly it becomes hilarious, I love to make people laugh with topics that used to make them uncomfortable, I love that it taught me that you can always laugh about shit when it happens and I love that (with a little bit of self-inflicted discipline) puts my ADHD to good use.
I think it's the perfect balance between insight and technique.
Do you get stage fright?
Back when I started, I used write "BREATHE" in big capital letters on my notes, so I would remember to do that while frantically reading and panicking before a set. Now that I'm more experienced I don't get it as much, but there's still a little bit of it, like a background noise. "Just enough to keep you focused" as a friend of mine says.
The cool thing is that it always goes away the very moment you start talking into the microphone.
