There were a lot of lessons of production to be learned. On the page, the biggest thing you learn on any TV show is how to write to your cast. You write the show at the beginning with certain voices in your head and you have a way that you think the characters will be, and then you have an actor go out there, and you start watching dailies and episodes. Then, you start realizing what they can do and what they can't do, what they're good at and what they're not so good at, how they say things and what fits in their mouth, and you start tailoring the voice of the show to your cast.

As frustrating as it gets, at times, and as frustrating as it is, at times, I don't think I've ever considered doing something else, or not wanted to do it anymore. To me, it's just the greatest job. It's a good fit for who I am and what I want to be.

Writing is like that. You have to have some basic creative spark, and then, if you have that, I feel like you can learn the production side of it. You can learn how to be a good producer. And I guess it does take a certain balance of those two skills in your head to be a successful showrunner.

When Kirk dies it was very emotional and very strange, in the moment and all the way through the process. I'd read it in the script and I'd always be struck by what I'd just done and what we were doing, and that this was my childhood hero and I was writing his death.

The creative part, with the writing of it and the vision, and finding the voice of a show and the characters, is much harder to teach somebody. It's like music. You can either play it or you can't. If you can't play music and you really struggle and work hard, you can learn, but you have to have some inner gift to take it to the next level.

Even then, I didn't quite know what to make of it [captain Kirk death]. I was mystified by why I was doing it, why I was so driven to do it, and why it was affecting me like it was. I still don't know what it means. It's a strange singular experience. I don't even know anyone to talk to about it because I don't know anyone who's had that experience.
