I think people are screw-ups, and even our greatest heroes are deeply flawed human beings. People make bad decisions for all the wrong reasons, and then somehow they'll do the right thing, and then somehow they'll save somebody, or they'll be compassionate. Horrible people can do wonderful things, and wonderful people can do horrible things.

There are definitely times when the outside eye can shine a light on something you weren't aware of. They're usually exposing a flaw or a problem. Sometimes they're saying, "Hey, this doesn't really work. Have you seen this?" And then, you go, "Oh, I didn't really see that. You're right, that doesn't work." If they're good, they shine a light on issues that you're blind to because you're too close to it.

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.

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.

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.

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.
