I write and write and write, and then I edit it down to the parts that I think are amusing, or that help the storyline, or I'll write a notebook full of ideas of anecdotes or story points, and then I'll try and arrange them in a way that they would tell a semi-cohesive story.
When I started out, I didn't feel like I was really accepted in the music or comedy communities, and I was somewhere on the edge, but now I feel like I'm accepted in both, which is extremely gratifying.
I like to think that I've gotten better at what I do. I spend more time and pay more attention to detail album after album. But pretty much it's stayed the same.
