The key things I learned as a hospital administrator are to be organized, communicate, and be flexible.

I created a show called 'Crash' for Starz, which was their first original drama, and that was not a good experience. I had a great time working with the cast and crew, but it was a young network and an intrusive studio, and to be honest I didn't really enjoy the movie 'Crash.

A lot of what I do as a showrunner is anxiety control. People get nervous when they don't know what's going on, so a big part of my job is making sure everyone has all of the information all of the time.

Don't forget, I've been fired by studios; I'm not the studio's guy. I'm a guy who can work with studios, but if you ask any studio, I stand up to these people.

People tweet me all the time and tell me how much they love it, how they can't wait for the show to come back on, that they're addicted to the show. So that's really rewarding. As an artist, we're all looking for that connection to an audience and when you find people as diehard as our fans are - it's sort of like finding the holy grail.

My time as showrunner on The Walking Dead has been an amazing experience, but after I finish season three, it’s time to move on. I have told the stories I wanted to tell and connected with our fans on a level that I never imagined. It doesn’t get much better than that. Thank you to everyone who has been a part of this journey.

That's the holy grail as a TV writer, to work on a story that you care about and to put it out there and for it to find the audience and connect with fans and connect with critics.
