If you don't have nerves and a little trepidation about any new project, then I don't think you're really alive.
I love writing, and I love the solitude of the writing, in that you're just sitting there creating something from nothing, or a new story for characters you love and care about.
I grew up in a family that was very barbed and difficult, and there was a lot of humor. None of it was painless humor. All of it was at someone else's expense. It was kind of always about power.
