I used to be an insult comic, and I didn't end up liking the way that I felt about myself.

There was an agent who wanted to book me for Glee. He lied and said I could sing. He was like, "If you need a guy in a wheelchair who has a great voice, I've got your guy!" I was like, "What are you talking about?" .

The thing to do is just make sure that as part of a disability community, we're not isolating ourselves by drawing differences for the sake of progress.

When I was a kid, I thought I would be an action-movie hero. I was like, "They're gonna be able to CGI my legs by that point." And then I realized that it was probably better if I stayed a little closer to who I actually am rather than trying to be Bruce Willis.

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."

Writing every day across nine time zones because Gillian [Grassie] was in Berlin, and we were working together via Skype. It was pretty intense. I'm really happy with how it turned out.

There's always going to be some hate on the Internet.
