You really just have to have a good attitude, challenge yourself, and you can accomplish great things.

When I read the script [of Glee], the whole premise was that all the high school kids were being cruel to this kid in the wheelchair, and then the quarterback comes along and has a heart of gold and takes him out of a Porta Potty. That's too often what I see in media, that the characters with disabilities are there to make other people seem like heroes for treating the character with a disability with respect. Those are the kinds of roles that are out there.

I do a lot of conferences, and I did a campaign with the Cerebral Palsy Foundation called "Just Say Hi." They get celebrities to record little messages about how you start a conversation with someone who has a disability, which is to "Just say hi."

Having a son with a disability helps makes Walter White a more sympathetic character. There's no story line that shows Walt Jr. going through the things that you go through as a teenager with a disability. It's always his relationship to other characters. That was my issue with it.

My friends from the University of Texas. I've had the same friends for over a decade. My brother films a lot; he usually edits my Workout Wednesdays. All the people who work on my projects are amazing.

We did a book signing and people came up to me. There was an expectant mother who was like, "I think we might name our child Zach because of your work."

I would love to get an international version of Riding Shotgun going, because that's what I've been angling at ever since I wanted to do a travel show in the first place.
