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.

After you get a season under your belt, you learn a lot of lessons. It's a much bigger challenge, logistically, in terms of production.

I'm always looking for vacation. I'm always trying to step away from it to watch movies. I'm always trying to carve out free time for myself. But, I love it. I don't think I've ever not wanted to run a show. When I have a show, I'm always really excited. I always enjoy the process.

Now I know that if I'm in a fight or a big argument with executives or the studio or whoever, and it's getting to a point where it's starting to get bad, I don't have to have the fear of, "Am I strong enough to see this through? Would I really make a stand here? Would I really quit over this issue?" And I know in my heart that there is a place where I would walk away. I don't have to make it about my ego. I don't have to make it about whether I'm being strong enough or tough enough.

When I finally got my break in TV, as a staff writer, I always wanted to be at the top of that pyramid. I always wanted to make the decisions. I always wanted to be the one that was saying, "This is what the show is, and this is what the show is not. This is where we're going. It's going to be this kind of series." It was just something I always had my eye on, when I started in the business.

I'm always tempted in the back of my mind to continue to write things in the Star Trek universe, in the novels or the comics, just because I don't get to play in that universe and I don't get to hang out with those characters any more. You spend hours upon hours of your life, day after day sitting in writers' rooms, talking about these people and these situations, and it becomes very real to you. They're friends of yours, in a lot of ways.

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.
